SunPy 2.0 Released

2020-06-12T00:00:00+00:00

The SunPy project is happy to announce the release of SunPy 2.0! SunPy is an open-source Python library for Solar Physics data analysis and visualization.

This release is our second long(er) term support release, that we will be supporting with bug fixes until 3.0 in roughly a year’s time. With this release, the 1.0 and 1.1 releases will no longer receive bug fixes and we encourage everyone to upgrade to 2.0.

The major highlights of this release are:

Fido now supports tab completion of search attributes. This allows you to do a.Instrument.AIA, and print a.Instrument to see the list of known supported instruments.
aiaprep has been deprecated in favor of the functionality in the aiapy package.
Various fixes and clarifications to pixel indexing in the sunpy.map subpackage.
Standardization of specifying rectangles in coordinate space in the submap() and draw_rectangle() methods of GenericMap.
HTML quicklook previews of GenericMap and MapSequence instances are available with the new quicklook() and quicklook() methods, respectively. This is also the default display in Jupyter notebooks.
Integration of differential rotation into the sunpy.coordinates framework. This enables, amongst other things, the warping of images with the reproject package and the plotting of rotated grid lines with WCSAxes.

See What’s New in SunPy 2.0 for more details and the Full Changelog for the full list of over 100 changes in 2.0.

This release of SunPy contains 1044 commits in 290 merged pull requests closing 144 issues from 33 people, 16 of which are first-time contributors to SunPy.

SunPy 1.0 Released

2019-06-01T00:00:00+00:00

The SunPy project is happy to announce the release of SunPy 1.0.0!

This release has been in development for 14 months, and is a large change from the 0.x series of SunPy releases with a lot of old functionality removed and some exciting new features.

The major highlights of this release are:

A complete transition of the whole code base to use astropy.time.Time, which was implemented by Vishnunarayan K I as part of Google Summer of Code 2018.
A rewrite of how all the clients in sunpy.net download files from the internet. This means vastly improved progress bars, skipping downloads if files are present, and better visibility and retrying of download errors.
A rewrite of the differential rotation and image warping code to correctly account for observer location using the Astropy coordinate functionality.
Removal of many deprecated functions and submodules; we have used the 1.0 release as a chance to clean out SunPy reducing the number of lines of Python code in the project by almost 3,000!
The first release of SunPy to be Python 3 only, requiring Python 3.6+.

See What’s New in SunPy 1.0 for more details and the Full Changelog for the full list of over 150 changes in SunPy 1.0.

This release includes many breaking changes and may require your code to be updated to support it. We hope you see the value in having the extra features these changes have enabled and a code base that is easier to maintain. We will be continuing to release bug fixes to the 0.9.z series until the end of 2019. We hope this gives you enough time to update your code and start enjoying all the improvements in SunPy 1.0.

If you use conda, you can update to this release by running:

$ conda install -c conda-forge sunpy

or, if you use pip, by running:

$ pip install -U sunpy

If you haven’t already installed SunPy we recommend you follow our Installation Guide.

By the numbers

This release of SunPy contains 1913 commits in 332 merged pull requests closing 582 issues from 46 people, 25 of which are first time contributors to SunPy.

On a personal note, I am very excited to see SunPy reach this milestone; watching the community around this project grow since I got involved has been incredible. The sunpy library is almost unrecognisable from where it was when I got involved shortly after the 0.2 release, which is the result of countless hours of work by over 100 people. I want to thank everyone who has contributed to SunPy in any way that helped us get to the point where we felt the library deserved the 1.0 label. I especially want to thank Nabil Freij who has done so much behind the scenes work to keep things moving forward, and done such a good job helping new contributors get pull requests into SunPy.

I am very excited to see where SunPy goes next.

Happy Pythoning,

Stuart

SunPy 0.9 Released

2018-04-24T00:00:00+00:00

The SunPy project is very happy to announce the release of SunPy 0.9, the latest release of the SunPy core package.

SunPy 0.9 brings improved support for downloading data from the JSOC and bugfixes compared to the 0.8.x series of releases. The 0.9.x series will be the last series of SunPy releases to support Python 2. This is because Python 2 will not be maintained after 2019. The 0.9.x series will receive bugfixs only up until the and of life of Python 2 (around 18 months). No new functionality will be added to the 0.9.x series, which will also be the last version to include sunpy.spectra, sunpy.lightcurve and sunpy.wcs, all of which were deprecated in 0.8.

SunPy 1.0 and higher will support Python 3 only. All new functionality will be available only in SunPy 1.0 and higher.

SunPy v0.9.0 contains 807 commits in 147 merged pull requests closing 310 issues from 31 people, 19 of which are first time contributors to SunPy.

The people who have contributed to the code for this release are

Nabil Freij

In addition to the contributions to the core SunPy library, we would like to thank Kolja Glogowski for his help with the JSOC project, and welcome his package ‘drms’ as a SunPy affiliated package, which is now powering our JSOC client. Finally, we would like to thank David Pérez-Suárez and Brigitta Sipocz, who are leading the GSOC process for OpenAstronomy, which is of massive benefit to the SunPy community.

SunPy 0.9 can be installed from pip or conda using the following commands

using conda:

$ conda config channels --append conda-forge
$ conda install sunpy

or using pip:

$ pip install sunpy

and updated using conda:

$ conda update sunpy

or pip:

NDCube 1.0 Released

2018-02-25T00:00:00+00:00

The SunPy project is very happy to announce the release of a new package “ndcube”.

ndcube is a package built for handling, inspecting and visualizing a wide variety of data, of any number of dimensions, along with coordinate information described by FITS-WCS. The NDCube object is based on the astropy NDData class, and adds functionality for slicing both the data and the WCS simultaneously, plotting with matplotlib and support for extra coordinate information along any of the axes not described by WCS.

In addition to this the ndcube package provides the NDCubeSequence class for representing sequences of NDCube objects where the coordinate information may or may not align, and accessing these sequences in a way consistent with a singular cube.

The ndcube development has been lead by Daniel Ryan with contributions from the following people:

Daniel Ryan
Ankit Baruah
Stuart Mumford
Mateo Inchaurrandieta
Nabil Freij
Drew Leonard
Shelbe Timothy

A lot of the design and development of ndcube was done as part of Ankit’s Google Summer of Code project in the summer of 2017.

For more information about ndcube see the documentation.

ndcube can be installed from pip or conda using the following commands:

$ conda install -c conda-forge ndcube

$ pip install ndcube

SunPy 0.7

2016-05-26T00:00:00+00:00

SunPy 0.7 has arrived! This release is a culmination of about 10 months of work from 27 different people. This release brings many changes, the highlights are:

Python 3.4 and 3.5 support. This is the first version of SunPy to support Python 3, we recommend that users start to consider moving to Python 3, please report any issues you may have.
New coordinate framework. The new sunpy.coordinates module provides a high-level interface to converting between different physical coordinate systems such as Helioprojective and Heliographic.
New draw_rectangle and draw_contours helpers for Map.
Support for masks in SunPy Map and MapCube.

For this version of SunPy we have started building our conda packages on the excellent conda forge service. This means you need to add the conda-forge channel to your conda installation. If you have never installed SunPy before we recommend you follow our installation instruction. If you are upgrading from a previous release run the following two commands if you installed via conda:

conda config --add channels conda-forge
conda upgrade sunpy

If you installed via pip then you can upgrade with:

pip install -U sunpy

SunPy 0.6 Released

2015-08-04T00:00:00+00:00

I am very happy to tell you that the long in the works 0.6.0 release of the SunPy library has arrived. This release has been ‘in the oven’ for well over a year, and is full of rather major changes.

The major changes in this release are:

Most functions throughout the SunPy code base now expect Astropy Quantity objects, and return Astropy Quantity objects.
Python 2.6 support has ended, we do not expect this release to work under Python 2.6.
Sample data has been removed from SunPy but helpers for downloading sample data have been added to sunpy.data.
TimeRange has a new property based API, e.g. start and end are now properties.
SunPy colormaps are now registered with matplotlib, allowing their use from imshow and similar functions after the import of sunpy.cm.
Solar rotation calculation functionality has been added, along with functionality to de-rotate MapCubes.

While there have been lots of changes, it is the move to Astropy Units throughout the code base that will require most users to update their code, if you wish to learn more about Astropy Units see: https://docs.astropy.org/en/latest/units/

You can install this release using either pip or conda. If you have a scientific python environment already configured, run:

pip install sunpy

or:

pip install --upgrade sunpy

if you have anaconda you need to add the sunpy and astropy channels to your conda config:

conda config --add channels sunpy --add channels astropy

and then run:

conda install sunpy

for more information about installing sunpy see our installation documentation: https://docs.sunpy.org/en/stable/tutorial/installation.html

This release consists of 1,341 commits from 29 different people and 13 new contributors!
