sunpy v1.1.0 (2020-01-10)

Backwards Incompatible Changes

  • The sunpy.net.vso.vso.get_online_vso_url function has been broken into two components, the new sunpy.net.vso.vso.get_online_vso_url function takes no arguments (it used to take three) and now only returns an online VSO mirror or None. The construction of a zeep.Client object is now handled by sunpy.net.vso.vso.build_client which has a more flexible API for customising the zeep.Client interface. (#3330)
  • Importing sunpy.timeseries.timeseriesbase no longer automatically imports Matplotlib. (#3376)
  • NOAAIndicesTimeSeries.peek now checks that the type argument is a valid string, and raises a ValueError if it isn't. (#3378)
  • Observer-based coordinate frames (~sunpy.coordinates.frames.Heliocentric and ~sunpy.coordinates.frames.Helioprojective) no longer assume a default observer (Earth) if no observer is specified. These frames can now be used with no observer specified, but most transformations cannot be performed for such frames. This removal of a default observer only affects sunpy.coordinates, and has no impact on the default observer in sunpy.map. (#3388)
  • The callback functions provided to ~sunpy.visualization.animator.BaseFuncAnimator button_func keyword argument now take two positional arguments rather than one. The function signature is now (animator, event) where the first arg is the animator object, and the second is the matplotlib mouse event. (#3407)
  • The colormap stored in SunPy's Map subclasses (ie. map.plot_settings['cmap']) can now be colormap string instead of the full matplotlib.colormap.Colormap object. To get the full Colormap object use the new attribute map.cmap. (#3412)
  • Fix a warning in sunpy.map.GenericMap.rotate where the truth value of an array was being calculated. This changes the behaviour of ~sunpy.map.GenericMap.rotate when the angle= parameter is not an ~astropy.units.Quantity object to raise TypeError rather than ValueError. (#3456)

Deprecations and Removals

  • Removed the step of reparing images (replacing non-finite entries with local mean) before coaligning them. The user is expected to do this themselves before coaligning images. If NaNs/non-finite entries are present, a warning is thrown. The function sunpy.image.coalignment.repair_image_nonfinite is deprecated. (#3287)
  • The method to convert a ~sunpy.coordinates.frames.Helioprojective frame from 2D to 3D has been renamed from ~sunpy.coordinates.frames.Helioprojective.calculate_distance to ~sunpy.coordinates.frames.Helioprojective.make_3d. This method is not typically directly called by users. (#3389)
  • sunpy.visualization.animator.ImageAnimatorWCS is now deprecated in favour of ~sunpy.visualization.animator.ArrayAnimatorWCS. (#3407)
  • sunpy.cm has been moved to sunpy.visualization.colormaps and will be removed in a future version. (#3410)

Features

  • Add a new sunpy.data.manager and sunpy.data.cache for dealing with versioned remote data within functions. Please see the Remote Data Manager guide. (#3124)
  • Added the coordinate frames ~sunpy.coordinates.frames.HeliocentricEarthEcliptic (HEE), ~sunpy.coordinates.frames.GeocentricSolarEcliptic (GSE), ~sunpy.coordinates.frames.HeliocentricInertial (HCI), and ~sunpy.coordinates.frames.GeocentricEarthEquatorial (GEI). (#3212)
  • Added SunPy Map support for GOES SUVI images. (#3269)
    • Support APE14 for ImageAnimatorWCS in SunPy's visualization module (#3275)
  • Add ability to disable progressbars when dowloading files using sunpy.net.helioviewer.py and edited docstrings to mention this feature. (#3280)
  • Adds support for searching and downloading SUVI data. (#3301)
  • Log all VSO XML requests and responses to the SunPy logger at the DEBUG level. (#3330)
  • Transformations between frames in sunpy.coordinates can now provide detailed debugging output. Set the logging level to DEBUG to enable this output. (#3339)
  • Added the sunpy.coordinates.sun.carrington_rotation_time function to compute the time of a given Carrington rotation number. (#3360)
  • A new method has been added to remove columns from a sunpy.timeseries.GenericTimeSeries. (#3361)
  • Add shape property to TimeSeries. (#3380)
  • Added ASDF schemas for the new coordinate frames (~sunpy.coordinates.frames.GeocentricEarthEquatorial, ~sunpy.coordinates.frames.GeocentricSolarEcliptic, ~sunpy.coordinates.frames.HeliocentricEarthEcliptic, ~sunpy.coordinates.frames.HeliocentricInertial). See the gallery for an example of using asdf to save and load a coordinate frame. (#3398)
  • sunpy.visualization.animator.ArrayAnimatorWCS was added which uses the WCS object to get the coordinates of all axes, including the slider labels. It also provides the ability to customise the plot by specifying arguments to ~astropy.visualization.wcsaxes.WCSAxes methods and supports animation of WCS aware line plots with Astroy 4.0. (#3407)
  • The returned list of ~sunpy.map.Map objects is now sorted by filename when passing a directory or glob pattern to ~sunpy.map.MapFactory. (#3408)
  • Single character wildcards and character ranges can now be passed as glob patterns to ~sunpy.map.Map. (#3408)
  • ~sunpy.map.Map now accepts filenames and directories as pathlib.Path objects. (#3408)
  • ~sunpy.map.GenericMap objects now have a .cmap attribute, which returns the full ~matplotlib.colormap.Colormap. object. (#3412)
  • sunpy.io.write_file() now accepts ~pathlib.Path objects as filename inputs. (#3469)
  • sunpy.map.make_fitswcs_header now accepts a tuple representing the shape of an array as well as the actual array as the data argument. (#3483)
  • Made a couple of module imports lazy to reduce the import time of sunpy.map by ~40%. (#3495)
  • sunpy.map.GenericMap.wcs now uses the full FITS header to construct the WCS. This adds support for instruments with more complex projections, such as WISPR, however does mean that Map will be more sensitive to incorrect or invalid FITS headers. If you are using custom headers with SunPy Map you might encounter issues relating to this change. (#3501)
  • sunpy.visualization.animator.BaseFuncAnimator now takes an optional slider_labels keyword argument which draws text labels in the center of the sliders. (#3504)
  • Added a more helpful error message when trying to load a file or directory that doesn't exist with Map. (#3568)
  • Add __repr__ for ~sunpy.map.MapSequence objects so that users can view the critical information of all the Map objects, in a concise manner. (#3636)

Bug Fixes

  • Fixed accuracy issues with the calculations of Carrington longitude (~sunpy.coordinates.sun.L0) and Carrington rotation number (~sunpy.coordinates.sun.carrington_rotation_number). (#3178)
  • Updated sunpy.map.header_helper.make_fitswcs_header to be more strict on the inputs it accepts. (#3183)
  • Fix the calculation of rsun_ref in ~sunpy.map.make_fitswcs_header and and ensure that the default reference pixel is indexed from 1. (#3184)
  • Fixed the missing transformation between two ~sunpy.coordinates.HeliographicCarrington frames with different observation times. (#3186)
  • sunpy.map.sources.AIAMap and sunpy.map.sources.HMIMap will no longer assume the existance of certain header keys. (#3217)
  • sunpy.map.make_fitswcs_header now supports specifying the map projection rather than defaulting to TAN. (#3218)
  • Fix the behaviour of sunpy.coordinates.frames.Helioprojective.calculate_distance if the representation isn't Spherical. (#3219)
  • Fixed a bug where the longitude of a coordinate would not wrap at the expected angle following a frame transformation. (#3223)
  • Fixed a bug where passing a time or time interval to the differential rotation function threw an error because the new observer was not in HGS. (#3225)
  • Fixed bug where ~sunpy.coordinates.ephemeris.get_horizons_coord was unable to accept ~astropy.time.Time arrays as input. (#3227)
  • Fix the ticks on the default heliographic grid overlay so they are not white (and normally invisible) by default. (#3235)
  • Fixed a bug with sunpy.net.hek.HEKClient when the results returned were a mixed dataset. (#3240)
  • Fix sunpy.physics.differential_rotation.differential_rotate to rotate in the correct direction and to account for the rotation of the heliographic coordinate frame with time. (#3245)
  • Fixed a bug with the handling of changing observation times for transformations between ~astropy.coordinates.HCRS and ~sunpy.coordinates.frames.HeliographicStonyhurst, which also indirectly affected other transformations when changing observation times. (#3246)
  • Fixed all coordinate transformations to properly handle a change in observation time. (#3247)
  • Fixed the handling of coordinates with velocity information when transforming between Astropy frames and SunPy frames. (#3247)
  • Fixed ~sunpy.physics.solar_rotation.calculate_solar_rotate_shift so that it does not calculate a shift between the reference layer and itself, which would sometimes incorrectly result in a shift of a pixel due to numerical precision. (#3255)
  • Stop crash when LineAnimator axes_ranges entry given as 1D array when data is >1D, i.e. as an independent axis. (#3283)
  • Fixed a sunpy.coordinates bug where a frame using the default observer of Earth could have its observer overwritten during a transformation. (#3291)
  • Fixed a bug where the transformation from ~sunpy.coordinates.frames.Helioprojective to ~sunpy.coordinates.frames.Heliocentric used the Sun-observer distance from the wrong frame when shifting the origin, and thus might not give the correct answer if the observer was not the same for the two frames. (#3291)
  • Fixed a bug with the transformations between ~sunpy.coordinates.frames.Heliocentric and ~sunpy.coordinates.frames.HeliographicStonyhurst when the frame observation time was not the same as the observer observation time. The most common way to encounter this bug was when transforming from ~sunpy.coordinates.frames.Helioprojective to any non-observer-based frame while also changing the observation time. (#3291)
  • VSO client fetch should not download when wait keyword argument is specified. (#3298)
  • Fixed a bug with ~sunpy.coordinates.wcs_utils.solar_frame_to_wcs_mapping that assumed that the supplied frame was a SunPy frame. (#3305)
  • Fixed bugs with ~sunpy.coordinates.wcs_utils.solar_frame_to_wcs_mapping if the input frame does not include an observation time or an observer. (#3305)
  • ~sunpy.coordinates.utils.GreatArc now accounts for the start and end points of the arc having different observers. (#3334)
  • Fixed situations where 2D coordinates provided to ~sunpy.coordinates.frames.HeliographicStonyhurst and ~sunpy.coordinates.frames.HeliographicCarrington were not converted to 3D as intended. Furthermore, the stored data will always be the post-conversion, 3D version. (#3351)
  • Fix off by one error in sunpy.map.make_fitswcs_header where when using the default reference_pixel=None keyword argument the pixel coordinate of the reference pixel was off by +1. (#3356)
  • Updated both GOES XRS and LYRA dataretriever clients to use ~sunpy.util.scraper.Scraper, to make sure that files are actually on the servers being queried. (#3367)
  • Fixing the ordering of lon and lat inputs into make_fitswcs_header (#3371)
  • Updated the URL for Fermi spacecraft-pointing files to use an HTTPS connection to HEASARC. (#3381)
  • Fixed a bug where permission denied errors when downloading files are very verbose by adding an error message in ~sunpy.net.fido_factory.UnifiedDownloaderFactory.fetch. (#3417)
  • Fixed a malformed call to astropy.time.Time in a test, which resulted in an incorrect time scale (UTC instead of TT). (#3418)
  • Fix incorrect files being included in the tarball, and docs missing from the tarball (#3423)
  • Fixed a bug where clipping behavior had been enabled by default in the plotting normalizers for Map objects. Clipping needs to be disabled to make use of the over/under/masked colors in the colormap. (#3427)
  • Fix a bug with observer based frames that prevented a coordinate with an array of obstimes being transformed to other frames. (#3455)
  • sunpy.map.GenericMap will no longer raise a warning if the posisition of the observer is not known for frames that don't need an observer, i.e. heliographic frames. (#3462)
  • Apply os.path.expanduser to sunpy.map.MapFactory input before passing to glob.glob (#3477)
  • Fix multiple instances of sunpy.map.sources assuming the type of FITS Header values. (#3497)
  • Fixed a bug with ~sunpy.coordinates.NorthOffsetFrame where non-spherical representations for the north pole produced an error. (#3517)
  • Fixed map.__repr__ when the coordinate system information contained in the CUNIT1/2 metadata is not set to a known value. (#3569)
  • Fixed bugs with some coordinate transformations when obstime is None on the destination frame but can be assumed to be the same as the obstime of the source frame. (#3576)
  • Updated sunpy.map.mapsequence.MapSequence so that calling _derotate() raises NotImplementedError. Added associated tests. (#3613)
  • Fixed pandas plotting registration in sunpy.timeseries. (#3633)
  • Correctly catch and emit a warning when converting a map metadata to a FITS header and it contains a keyword with non-ascii characters. (#3645)

Improved Documentation

  • Clean up the docstring for sunpy.physics.differential_rotation.solar_rotate_coordinate to make the example clearer. (#2708)
  • Added new gallery examples and cleaned up various gallery examples. (#3181)
  • Cleaned and expanded upon the docstrings for each Fido Client. (#3220)
  • Added clarifying hyperlinks to the gallery example getting_lasco_observer_location to link to astroquery docs page. (#3228)
  • Added more details to docstrings in sunpy.coordinates.frames. (#3262)
  • Added a link to package maintainer list in the API Stability page. (#3281)
  • Improved the contributing guide by updating commands and highlighting text. (#3394)
  • Removing .fits from the end of path kwargs in sunpy.net.FIDO.fetch docs to change output file extension from {file}.fits.fits to {file}.fits. (#3399)
  • A new example gallery section "Using SunPy with Other Packages" has been added, which contains a set of new examples using the reproject with solar data. (#3405)
  • Added a table of supported coordinate systems and other miscellaneous improvements to the :ref:`coordinates documentation <sunpy-coordinates>`. (#3414)
  • Clarified the meaning of :attr:`GenericMap.dsun`. (#3430)
  • Fixed the plots with multiple subplots in the Map user guide to properly use ~astropy.visualization.wcsaxes and to be appropriately sized. (#3454)
  • Fixed various issues with the gallery example of saving/loading coordinates using asdf. (#3473)
  • Added sunpy.__citation__ with a BibTex entry for citing sunpy. (#3478)
  • Added an example showing how to display two maps and fade between them. (#3488)
  • Clarified the meaning of some GenericMap observer properties. (#3585)
  • Added inherited members of sunpy.map classes to the docs. (#3587)
  • Fixed documentation of sunpy.database.Database.search by adding Returns docstring. (#3593)
  • Updated the docstring for the parameter sortby in ~sunpy.map.MapSequence with the default value, valid value and how to disable sorting. (#3601)
  • Updated the tour guide to reflect that the time series is not random data. (#3603)
  • Fixes bold type and extra line breaks of remote data manager example in remote_data_manager.py. (#3615)

Trivial/Internal Changes

  • Allow running our sphinx-gallery examples as Jupyter notebooks via Binder (#3256)
  • Improve error messages and type checking in sunpy.visualization.animator.image.ImageAnimatorWCS. (#3346)
  • Copy the library distro into sunpy/extern: replaces the deprecated platform/linux_distribution (#3396)
  • The version of Matplotlib used to generate figure tests has been bumped from 3.0.3 to 3.1.1. (#3406)
  • Corrected spelling of 'plotting' in timeseries method (changed 'ploting' to 'plotting'). (#3429)
  • Switched to "importlib_metadata" to get package version to speed up import of SunPy. (#3449)
  • Fix tests for sunpy.data.data_manager and ensure they are correctly executed with pytest. (#3550)

sunpy 1.0.0 (2019-06-01)

Backwards Incompatible Changes

  • Move the matplotlib animators from sunpy.visualisation.imageanimator and sunpy.visualization.mapcubeanimator to sunpy.visualization.animator. (#2515)
  • Make sunpy.time.parse_time return astropy.time.Time instead of datetime.datetime. (#2611)
  • The properties and methods of sunpy.time.TimeRange returns astropy.time.Time and astropy.time.TimeDelta instead of datetime.datetime and datetime.timedelta respectively. (#2638)
  • The sunpy.instr.goes module now accepts and returns sunpy.timeseries.XRSTimeSeries objects only. (#2666)
  • obstime keyword param of sunpy.instr.goes._goes_lx takes a non-scalar astropy.time.Time object instead of numpy.ndarray. The precision of times contained in sunpy.timeseries has been increased to 9 from 6. (#2676)
  • Removed sunpy.net.jsoc.attrs.Time because it served the same purpose as sunpy.net.attrs.Time after the switch to astropy.time.Time. (#2694)
  • Remove unused **kwargs within TimeSeries functions. (#2717)
  • Rotation matrices inside map objects were previously stored as numpy matrices, but are now stored as numpy arrays, as numpy will eventually remove their matrix datatype. See https://docs.scipy.org/doc/numpy/user/numpy-for-matlab-users.html for more information. (#2719)
  • The sunpy.cm.show_colormaps function now accepts the keyword 'search' instead of 'filter'. (#2731)
  • The keyword arguments to all client .fetch methods have been changed to support the new parfive downloader and to ensure consisteny across all Fido clients. (#2797)
  • The Helioviewer client has been switched to using the newer Helioviewer API. This has meant that we have changed some of the keywords that were passed into client's methods. We have enforced that several keywords (observatory,instrument,detector,measurement) need to be defined otherwise the functions cannot return any data. (#2801)
  • Maps no longer assume that the pixel units are arcseconds if the units aren't explicitly set. In addition to this if critical metadata is missing from when creating a map, the map will fail to initialize and will raise an error. (#2847)
  • axis_ranges kwarg of sunpy.visualization.animator.base.ArrayAnimator, sunpy.visualization.animator.image.ImageAnimator and sunpy.visualization.animator.line.LineAnimator now must be entered as None, [min, max] or pixel edges of each array element. Previously, pixel centers were expected. This change removes ambiguity in interpretation and ensures the extent of the plot can always be accurately derived. (#2867)
  • All keywords have been added (with defaults) to each ~sunpy.net.helioviewer.HelioviewerClient function. This means that there will be some changes to the style of the PNG screenshot that is returned. Returns for the JPEG 2000 and the other functions should be the same but not guaranteed. (#2883)
  • Changed sunpy.sun.models.interior and sunpy.sun.models.evolution from pandas.DataFrame to astropy.table.QTable (#2936)
  • Minimum numpy version is now >=1.14.5 (#2954)
  • Removed sunpy.time.julian_day, sunpy.time.julian_centuries, sunpy.time.day_of_year, sunpy.time.break_time, sunpy.time.get_day. (#2999)
  • Updated the solar values in sunpy.sun.constants to IAU 2015 values. (#3001)
  • Renamed eccentricity_sunearth_orbit to eccentricity_sun_earth_orbit. (#3001)
  • Renamed sunpy.image.rescale to sunpy.image.resample. (#3044)
  • Remove the basic_plot keyword argument from ~sunpy.map.Map.GenericMap.peek. An example has been added to the gallery showing how to make a plot like this. (#3109)
  • sunpy.map.GenericMap will no longer use the key solar_b0 as a value for heliographic latitude. (#3115)
  • sunpy.map.GenericMap now checks for a complete observer location rather than individually defaulting coordinates (lat, lon, distance) to Earth position. If any one of the three coordinates is missing from the header the observer will be defaulted to Earth and a warning raised. (#3115)
  • sunpy.sun.sun functions have been re-implemented using Astropy for significantly improved accuracy. Some functions have been removed. (#3137)
  • All of the functions in sunpy.sun.sun and all of the Sun-specific functions in sunpy.coordinates.ephemeris have been moved to the new module sunpy.coordinates.sun. (#3163)

Deprecations and Removals

  • The deprecated sunpy.lightcurve, sunpy.wcs and sunpy.spectra modules have now been removed. (#2666)
  • sunpy.instr.rhessi.get_obssumm_dbase_file sunpy.instr.rhessi.get_obssum_filename, sunpy.instr.rhessi.get_obssumm_file have been removed. Fido <sunpy.net.fido_factory.UnifiedDownloader> should be used to download these files. (#2808)
  • Removed heliographic_solar_center in favour of ~sunpy.coordinates.ephemeris.get_sun_L0 and ~sunpy.coordinates.ephemeris.get_sun_B0 (#2830)
  • Removed GenericClient.query in favour of sunpy.net.dataretriever.GenericClient.search (#2830)
  • Removed sunearth_distance in favour of get_sunearth_distance (#2830)
  • Removed remove_lytaf_events_from_lightcurve in favour of sunpy.instr.lyra.remove_lytaf_events_from_timeseries (#2830)
  • Removed sunpy.cm.get_cmap in favour of plt.get_cmap (#2830)
  • Removed database.query in favour of sunpy.database.Database.search (#2830)
  • Removed sunpy.net.vso.InteractiveVSOClient (#2830)
  • Removed MapCube in favour of ~sunpy.map.MapSequence (#2830)
  • Removed solar_north in favour of get_sun_P (#2830)
  • Removed database.download in favour of sunpy.database.Database.fetch (#2830)
  • Removed sunpy.map.GenericMap.pixel_to_data in favour of sunpy.map.GenericMap.pixel_to_world (#2830)
  • Removed GenericClient.get in favour of sunpy.net.dataretriever.GenericClient.fetch. This changes applies to the other clients as well. (#2830)
  • Removed Map.xrange and Map.yrange (#2830)
  • Removed sunpy.net.attrs.Wave in favour of a.Wavelength <~sunpy.net.vso.attrs.Wavelength> (#2830)
  • Removed JSOCClient.check_request in favour of drms.ExportRequest.status (#2830)
  • sunpy.net.vso.VSOClient.query_legacy and sunpy.net.vso.VSOClient.latest have been deprecated as we strongly recommend people use sunpy.net.Fido for all queries. (#2866)
  • The deprecated sunpy.physics.transforms module has been removed, it is replaced by sunpy.physics.solar_rotation and sunpy.physics.differential_rotation. (#2994)
  • Removed ~sunpy.sun.sun.solar_cycle_number because it was fundamentally flawed (#3150)

Features

  • Change arguments to sunpy.test from offline= and online= to online and online_only. This matches the behavior of the figure keyword arguments and comes as a part of a move to using a modified version of the Astropy test runner. (#1983)
  • asdf schemas and tags were added for the SunPy coordinate frames and ~sunpy.map.GenericMap allowing these objects to be saved to and restored from asdf files. (#2366)
  • The images from image tests are now saved in a local folder for easy access. (#2507)
  • sunpy.map.MapCube has been renamed to sunpy.map.MapSequence to better reflect its use as a collection of map objects. (#2603)
  • Net search attributes now support tab completion of values and display a table of possible values when printed, to allow easier discoverability of possible search values. (#2663)
  • Running the figure tests now creates a page showing the differences between the expected figures and the figures produced from running the tests. (#2681)
  • Add support for Dask arrays in sunpy.map.Map. The map factory now checks a whitelist of array types rather than strictly checking if the array is of type numpy.ndarray. (#2689)
  • Persist the name of a coordinate, i.e. "earth" even though a concrete coordinate object has been calculated and use this string representation to change the way the sunpy frames are printed. This is primarily to facilitate displaying the name of the body rather than the concrete coordinate when printing a ~astropy.coordinates.SkyCoord. (#2723)
  • ~sunpy.net.hek.HEKClient.search now returns an astropy.table.Table instead of list of a dict. (#2759)
  • Add a downscaled HMI image to the sample data. (#2782)
  • Now able to create a sunpy.map.Map using an array and a astropy.wcs.WCS object. (#2793)
  • The download manager for Fido.fetch <sunpy.net.fido_factory.UnifiedDownloader.fetch> has been replaced with parfive. This provides advanced progress bars, proper handling of overwriting and the ability to retry failed downloads. (#2797)
  • sunpy.map.GenericMap can now save out rice compressed FITS files. (#2826)
  • Now any SunPyDeprecationWarnings will cause an error when using pytest. (#2830)
  • Added full Tox support for SunPy tests, documentation build and figure tests. (#2839)
  • Transition the sunpy.net.vso.VSOClient from using suds to zeep as the SOAP library. This is a more actively maintained library, and should provide better support for the VSOs https endpoints. This change should have no effect on the public API of the sunpy.net.vso.VSOClient. (#2866)
  • Provided access to the Helioviewer header information using ~sunpy.net.helioviewer.HelioviewerClient.get_jp2_header function. (#2904)
  • Add a new WSDL URL and port to support SunPy use of VSO instance at SDAC. (#2912)
  • Add support for COSMO K-Coronograph (KCOR) FITS data. (#2916)
  • Add logger messaging system based on ~astropy.logger.AstropyLogger, cleaned up all warnings, removed all print statements. (#2980)
  • The function sunpy.image.coalignment.get_correlation_shifts now issues an error when the number of dimensions are not correct instead of a warning and returning None. (#2980)
  • The default location of the sunpy sample data has changed to be in the platform specific data directory as provided by appdirs. (#2993)
  • Add timeseries support for EVE/ESP level 1 data in sunpy.timeseries.sources.eve (#3032)
  • The default style for Map plots have changed to reflect the changes in Astropy 3.2. (#3054)
  • sunpy.coordinates.ephemeris.get_body_heliographic_stonyhurst can now account for light travel time when computing the (apparent) body position, as long as the observer location is provided. (#3055)
  • Added a helper function (sunpy.map.make_fitswcs_header) that allows users to create a meta header for custom created sunpy.map.GenericMap. (#3083)
  • Map plotting now accepts the optional keyword clip_interval for specifying a percentile interval for clipping. For example, if the interval (5%, 99%) is specified, the bounds of the z axis are chosen such that the lowest 5% of pixels and the highest 1% of pixels are excluded. (#3100)
  • The new function ~sunpy.coordinates.get_horizons_coord enables querying JPL HORIZONS for the locations of a wide range of solar-system bodies, including spacecraft. (#3113)

Bug Fixes

  • Fix the bug that prevented VSO queries for HMI data from downloading file without specifying a.Physobs. (#2621)
  • Fix sunpy.map.mapcube.MapCube.plot. The code had not been updated to support the changes to the wcsaxes helper functions. (#2627)
  • Replace all use of the deprecated sunpy.cm.get_cmap with matplotlib.pyplot.get_cmap to prevent deprecation warnings being raised. (#2635)
  • Fix generation of the coordinate transformation graph with Astropy 3.1.dev (#2636)
  • Prevent helioviewer from erroring when downloading file to a directory that does not exist. It will now create the directory when required. (#2642)
  • Fix transformations into/out of Heliographic Stonyhurst frame when the coordinate representation is Cartesian. (#2646)
  • Running the figure tests with setup.py test now saves the figures and the hashes to the same directory as setup.py. (#2658)
  • sunpy.instr.fermi.met_to_utc now returns the correct utc time which takes into account the leap seconds that have passed. (#2679)
  • Support passing Python file objects to sunpy.io.fits.write. (#2688)
  • Added DRMS to setup.py so sunpy[all] installs it as a dependancy. (#2693)
  • Fix eve 0cs timeseries seperator regex to support Python 3.7 (#2697)
  • Fix the bug which crashes ~sunpy.map.sources.LASCOMap for when 'date-obs' is reformatted agian from a self applied function. (#2700)
  • Change all instances of quantity_allclose to astropy.units.allclose this prevents pytest being needed to import sunpy.coordinates on Astropy 3 (#2701)
