Python in Heliophysics Community (PyHC)

Announcing PHEP 3

Tue, 02 Dec 2025 00:00:00 +0000

PyHC has formally adopted PHEP 3: PyHC Python & Upstream Package Support Policy! This new PHEP establishes a unified, time-based approach to dependency support across the PyHC ecosystem, bringing our community into alignment with the broader Scientific Python ecosystem.

PHEP 3 recommends that all PyHC packages adopt the following support policy, based on SPEC 0:

Support Python versions for 36 months (3 years) after their initial release
Support core Scientific Python packages for 24 months (2 years) after their initial release
Adopt new versions within 6 months of their release

This policy applies to Python itself and to the upstream core Scientific Python packages: NumPy, SciPy, Matplotlib, pandas, scikit-image, NetworkX, scikit-learn, xarray, IPython, and Zarr.

To learn more, read the full PHEP 3 document. We will also maintain a PHEP 3 Support Schedule page with a graphical timeline and quarterly reminders to help package maintainers stay on track. Questions or feedback? Join the discussion on PyHC’s mailing list or Slack!

Introducing the PyHC Documentation Hub!

Wed, 12 Mar 2025 00:00:00 +0000

We’re excited to announce the launch of the PyHC Documentation Hub, now available at pyhc.org/pyhc-docs. This centralized resource simplifies how you search across documentation for all PyHC packages that use Read The Docs. No more switching between dozens of disparate package websites to find the information you need. The Hub not only links all packages together in one convenient place but also provides a powerful search interface that organizes results by package for easy navigation. Find documentation faster than ever—we hope you find it useful. Try it out today!

Poster Abstract Submission Open for the PyHC 2024 Summer School

Thu, 21 Mar 2024 00:00:00 +0000

As a reminder, the Python in Heliophysics Community (PyHC) 2024 Summer School is set to take place Monday, May 20th to Friday, May 24th at the prestigious Laboratory for Atmospheric and Space Physics (LASP) in scenic Boulder, Colorado, USA and online on Zoom. This year’s Summer School builds on the foundational success of its predecessor, offering an even deeper dive into the rich ecosystem of Heliophysics Python packages. Open to undergraduate and graduate students, early career scientists, and anyone eager to deepen their understanding of Python in the Heliophysics and Space Weather disciplines, this program promises a mix of in-depth tutorials, engaging demos, and hands-on sessions, delivered by some of the field’s leading experts. If you have not yet registered for the summer school, it is free to do so and a link for it can be located on the summer school’s web page. You’ll also find there a link to suggesting housing, NSF travel support applications, specific location, the agenda, and other important information.

If you plan to attend the PyHC 2024 summer school on site in Boulder, CO at LASP, and are interested in presenting on your work within Heliophysics/Space Physics and Python, the summer school poster session is your best bet! Bonus points if you can show work you’ve done that leverages the PyHC ecosystem. We have created a Google form to which you can submit your abstracts for the poster session, which will help the organizing committee adequately plan for the poster session, and ensure all submissions are on topic.

Submit PyHC 2024 summer school poster abstracts here. Deadline for abstract submission is Monday, May 6th, 2024 at 11:59 PM MT.

NSF Travel Support for the PyHC 2024 Summer School

Tue, 06 Feb 2024 00:00:00 +0000

The Python in Heliophysics Community (PyHC) is thrilled to announce that we were awarded $50k of NSF travel support to provide to selected attendees of the PyHC 2024 summer school! Per NSF policy, only US citizens and those with lawful permanent resident (LPR) status are eligible for the stipend.

Travel support applications will be vetted and approved by the summer school planning committee. Applications will be scored on need (whether the travel grant strongly determines their ability to attend onsite), career stage (student, post-doctoral, early career, or within 5 years of most recent degree given preference), and equity (ensuring travel funds are disbursed to multiple institutions, rather than focusing on large cadres from the same institution).

Funding specifications: Once applications have been reviewed, we will award flat-rate travel stipends of $2000 - $2500 (depending on home institute location) to selected attendees. These awards will be sent out as reimbursements for the meeting, therefore the attendee will have to float the cost up to that point.

Apply for the NSF-sponsored travel funding here. Applications are due by Monday, April 29th, 2024.

PyHC Spring 2024 Meeting Dates Announced

PyHC serves as a community knowledge base for performing heliophysics research in Python, aiming to provide a variety of tutorials and resources, a list of useful packages, general discussion, and advice. Twice yearly, PyHC meets in person. These meetings are open to anyone, from individuals already utilizing Python heavily in developing open-source heliophysics packages to those who are just getting into using Python and open source development.

PyHC’s first meeting of 2024 will be held remotely on Zoom. The meeting will run Monday, March 11th, 2024 – Thursday, March 14th, 2024, from 9 AM – 11 AM MT each day. The Zoom sessions will be recorded. Expect excellent discussion opportunities, core project updates, and other related talks and demos! See the full agenda for dates/times of the various sessions. The agenda is currently being finalized, and thus is subject to change.

The meeting’s web page can be found here. Registration—which is free but required—can be found here. The meeting’s web page also has a link to registration, as well as the Zoom telecon information, links to important documents, etc. If you’d like to join our mailing list to learn more information about the meeting and other upcoming events, please see the PyHC Contact page for instructions. You’ll also find links there for joining our Element and Helionauts chat groups (where we discuss various PyHC issues/topics, as well as discussing other Python-related questions), as well as a link to connect with PyHC on Twitter!

Registration Deadline: EOD, Friday, March 8th, 2024. Note: If you already registered and later decide to change your registration, you should be able to do that directly, but if you experience any difficulties please email Julie Barnum or Shawn Polson.

New Way To Cite PyHC

Thu, 05 Jan 2023 00:00:00 +0000

You can now uniquely identify PyHC as an entity with this ROR ID:
https://ror.org/012prn105

ROR is a global, community-led registry of open persistent identifiers for research organizations. ROR IDs function much like DOIs but they are used for research organizations rather than individual research outputs. Learn more about ROR IDs on their website. Let’s spread the word about this new citation mechanism!

New Website URL!

Fri, 08 Jul 2022 00:00:00 +0000

We are excited to announce that we have purchased the pyhc.org domain. A very special thanks is owed to Pete Riley with Predictive Science Inc. for making the purchase and handling the renewals. At present, pyhc.org redirects to our original heliopython.org. This will remain the case during a transition period until we fully move the website to the new domain, at which time heliopython.org will start redirecting to pyhc.org. Please note that HTTPS support has not yet been added to the new domain, so https://pyhc.org will fail to redirect but http://pyhc.org will succeed. This is only temporary and it is not a security concern because redirects are still sent to the secure https://heliopython.org.
