Breaking Changes

  • Dataretriever / "Scraper" clients no longer require the regex-formatted baseurl and a parse-formatted pattern variable but instead a single and full pattern variable written in the parse-format. Documentation about how to write the new patterns and about explaining the internal Scraper algorithm is added to the topic guide on adding new sources to Fido.

    The internal method on ~sunpy.net.scraper.Scraper called _extract_files_meta function no longer requires an extractor pattern.

    A new submodule called scraper.net.scraper_utils is created and Scraper helper functions like date_floor(), extract_timestep(), check_timerange() and get_timerange_from_exdict() can be accessed directly from there.

    All the extracted timeranges have a millisecond subtracted from the end date, i.e. they end on 59:59:59 of the date just before, instead of the inconsistent issue where some could end with 00:00:00 of the end date which lead to undesirable cases like January 1, 2015 data also showing up in the 2014 year-long timerange. (#7077)

  • Update our dependancy policy to follow SPEC 0 rather than the older NEP 29. The only difference between the old (NEP 29) policy and the new (SPEC 0) policy is that we only support Python versions for 3 years after their initial release, rather than 4. (#7796)

  • Increased minimum versions for these dependencies:

    • asdf-astropy >= 0.5.0
    • astropy >= 6.0.0
    • numpy >= 1.24.0
    • pandas >= 1.5.0
    • sphinx >= 6.0.0 (#7976)

Deprecations

  • sunpy.map.GenericMap.contour is deprecated in favor of sunpy.map.GenericMap.find_contours. Note that ContourPy, now used for contour generation, may produce different results and does not support all scikit-image keyword arguments. (#7760)
  • The following components of ~sunpy.map.MapSequence are now deprecated and will be removed in v7.1:
    • The derotate keyword argument to ~sunpy.map.MapSequence. Derotation is not implemented.
    • The resample keyword argument to ~sunpy.map.MapSequence.peek and ~sunpy.map.MapSequence.plot. To reproduce this behavior, use ~sunpy.map.GenericMap.resample on each map in the sequence before plotting.
    • Deprecate ~sunpy.map.MapSequence.all_maps_same_shape in favor of ~sunpy.map.MapSequence.all_same_shape.
    • Deprecate ~sunpy.map.MapSequence.at_least_one_map_has_mask. To reproduce this functionality, check whether ~sunpy.map.MapSequence.mask is None.
    • Deprecate ~sunpy.map.MapSequence.as_array in favor of ~sunpy.map.MapSequence.data and ~sunpy.map.MapSequence.mask. Previously, as_array returned a masked array if at least one map held a mask and a bare array if not.
    • Deprecate ~sunpy.map.MapSequence.all_meta in favor of ~sunpy.map.MapSequence.meta. (#7827)
  • General support within ~sunpy.map.Map for the non-standard CTYPE values 'SOLAR-X' and 'SOLAR-Y' is now deprecated, and should instead be handled by a source-specific subclass. (#7955)
  • Renamed the sunpy.time.TimeRange method extend() to sunpy.time.TimeRange.shift to reflect what the method actually does. (#8008)

New Features

  • Added support for saving a sunpy.map.Map into an ASDF file using sunpy.map.GenericMap.save and loading a map stored in an ASDF file with sunpy.map.Map. (#7712)
  • The ~sunpy.coordinates.RotatedSunFrame class now accepts a ~astropy.time.TimeDelta object for the duration parameter. (#7752)
  • Added ~sunpy.map.GenericMap.find_contours for getting contours from a ~sunpy.map.Map. By default the method uses ContourPy for performance reasons and consistency with sunpy.map.GenericMap.draw_contours. One can alternatively specify that the method use scikit-image. (#7760)
  • Added support for loading files from various cloud services (such as s3) in ~sunpy.map.Map and ~sunpy.timeseries.TimeSeries using fsspec. (#7790)
  • Added the ~sunpy.coordinates.HelioprojectiveRadial coordinate frame. (#7803)
  • Added a function ~sunpy.map.make_hpr_header to easily make a FITS WCS header for the ~sunpy.coordinates.HelioprojectiveRadial coordinate frame. (#7803)
  • Added a function sunpy.visualization.show_hpr_impact_angle to modify a plot axis of a ~sunpy.coordinates.HelioprojectiveRadial ~sunpy.map.Map to show impact angle rather than declination for the tick labels. (#7803)
  • Added ability to delay download in sunpy.data.data_manager.manager.DataManager.require (#7845)
  • Add sunpy.visualization.drawing.extent to visualize the extent of another WCS on an axis. Add sunpy.map.GenericMap.draw_extent to visualize the extent of a map on a given axis. (#7851)
  • Add a link to the VSO Health Report in the Fido Results when using the VSOClient. (#7884)
  • Added unconverted_value attribute to the Wavelength attribute. (#7923)
  • sunpy.time.TimeRange.shift can now accept inputs of type datetime.timedelta and astropy.units.Quantity. (#7931)
  • sunpy.map.CompositeMap.plot will now skip autoaligning an overplotted map image if that map's WCS matches the WCS of the figure axes. This significantly improves performance when the maps being composited have already been reprojected onto a common WCS. (#7948)

Bug Fixes

  • sunpy.map.MapSequence unable to set the normalization for data that was UINT8 (JPEG2000) causing the animations to break. (#7674)

  • Fixed incorrect reference_date for GONG Synoptic maps. (#7758)

  • Fix sunpy.physics.differential_rotation.differential_rotate to update the reference_date attribute of the input map instead of the date. (#7758)

  • Fixed incorrect reference_date for SDO/AIA and SDO/HMI data to use the T_OBS keyword instead of the DATE-OBS keyword.

    For AIA images, the location of SDO has been shifted up to a second in time, which corresponds to a shift in Heliographic Longitude by only 4 milliarcseconds. (#7758)

  • Fix filetype detection to use the detected filetype if a known reader is registered. (#7788)

  • Fixed loading of ~sunpy.map.sources.ADAPTMap if sunkit-magex v1.0.0 is installed. (#7798)

  • All map sources that override date or reference_date now fall back to the corresponding properties on sunpy.map.GenericMap if the needed source-specific metadata for these properties cannot be found. (#7810)

  • Fixes a bug where ~sunpy.map.sources.HMIMap returned a wavelength without a unit because WAVEUNIT is not in the header and cannot be parsed from any other part of the metadata. If it cannot be found, it now defaults to Angstrom. (#7812)

  • Fixed a calculation bug when using ~sunpy.coordinates.PlanarScreen when it is both tilted (the plane is not perpendicular to the observer-Sun direction) and offset (the plane does not go through Sun center). (#7814)

  • Fixed a bug where custom values in the plot_settings dictionary were not being correctly applied in the sunpy.map.GenericMap.draw_contours method. (#7844)

  • Fix use of deprecated astropy.table.Table.pformat_all in sunpy.net. (#7854)

  • Fixed a bug with axis labels when plotting a ~sunpy.map.Map that could conflict with automatic label positioning in astropy 7.0. (#7857)

  • Added correct unit fallback for LASCO JPEG2000 files from the Helioviewer. (#7890)

  • Added support within ~.parse_time for the timestamp %Y%m%d%H%M ,%Y%m%dT%H%M and %Y%m%d_%H%M. (#7911)

  • Updated the internal CDF reader to handle FILLVAL only for floating point numbers. (#7917)

  • Fixed unit conversion for wavelength in sunpy.net.dataretriever.sources.goes.SUVIClient. (#7920)

  • Fixed a time-ordering bug in sunpy.time.TimeRange.shift when the shifted start time is later than than the shifted end time. (#7931)

  • Fixed a bug in the HTML representation for sunpy.timeseries.GenericTimeSeries that error-ed if the time-series had too many columns. (#7947)

  • Fix sunpy.data.data_manager.manager.DataManager.get now automatically redownloads files if they are accidentally deleted. (#7950)

  • Fixed a bug in ~sunpy.physics.differential_rotation.differential_rotate that assumed the input map header had RSUN_REF defined. (#7953)

  • Fixed two bugs associated with the handling of WCS PVi_m values by ~sunpy.map.Map. PVi_m values were incorrectly retrieved from the first alternative WCS description (e.g., PV1_1A) instead of the primary WCS description (e.g., PV1_1). Also, PVi_m values were misassigned when m was a two-digit number (i.e., 10 through 99). (#7961)

  • Fixed a bug in ~sunpy.time.parse_time where parsing a list of time strings containing "TAI" did not automatically set the time scale to TAI. (#7983)

  • Fixed a bug in ~sunpy.time.parse_time where parsing a list of time strings could incorrectly fail even when parsing the individual elements would succeed. (#7983)

  • Fixed the formatting of the the channel labels for ~sunpy.timeseries.sources.XRSTimeSeries. (#7986)

  • Examples in docs for sunpy.net.attr.Attr are now rendering properly. (#8002)

  • Fixed the unintended ~sunpy.map.Map behavior where any combination of non-FITS units were allowed as long as one of the non-FITS units was DN. DN is currently the only non-FITS unit permitted in ~sunpy.map.Map. (#8037)

  • Corrected the NOAA ~.SRSClient to use a updated HTTPS server instead of the now defunct FTP. (#8054)

  • Fixed a bug where ~sunpy.map.sources.EITMap and the correct colormaps (e.g., sohoeit171) failed to load for SOHO/EIT level 1 FITS files from SDAC. (#8070)

Documentation

  • Added a topic-guide <sunpy-topic-guide-deprecation-versioning> describing deprecation and versioning policies alongside release practices for users and developers. (#7731)
  • Added a gallery example (sphx_glr_generated_gallery_map_track_active_region.py) showcasing how to track an active region. (#7735)
  • Added a gallery example (sphx_glr_generated_gallery_saving_and_loading_data_load_adapt_fits_into_map.py) showcasing how to load an Air Force Data Assimilative Photospheric Flux Transport (ADAPT) FITS file into a list of sunpy.map.Map. (#7756)
  • Fixed a bunch of broken links in the documentation. (#7766)
  • Added a new how-to guide sunpy-how-to-observer-by-coordinate demonstrating how to create coordinate objects with an observer location specified using ~astropy.coordinates.SkyCoord. (#7769)
  • Reworked the sphx_glr_generated_gallery_plotting_screen_blend_mode.py example so that it no longer requires an additional dependency (mplcairo) (#7800)
  • Add clarifications to install instructions about Anaconda and the defaults channel. (#7813)
  • The gallery example sphx_glr_generated_gallery_units_and_coordinates_STEREO_SECCHI_starfield.py now queries the Gaia star catalogue directly instead of going through Vizier. (#7965)
  • Added a note to the docstring of ~sunpy.map.sources.sdo.HMISynopticMap that documents how the sign of CDELT1 is handled. (#7973)
  • Added a table and notes to show which methods from ~sunpy.map.GenericMap are expected to preserve laziness with dask arrays. (#7974)
  • Updated sphx_glr_generated_gallery_time_series_goes_xrs_nrt_data.py to plot the largest flares that occurred during GOES XRS NRT data. (#7981)

Internal Changes

  • Removed mplcairo as a dependency for building the documentation. (#7800)
  • Fixed some regex bugs in ~sunpy.time.parse_time that could result in additional, spurious matches for the candidate string format. There is a minor performance impact for each spurious match that is attempted to be used for parsing. (#7983)
  • Added clarification to the docstring for the .GenericMap.measurement property about its possible return types. (#8038)
