Infographic showing how the Solar Orbiter spacecraft traces superfast electrons back to their sources on the Sun. The Sun is depicted on the left, with colored dots representing sources of energetic electrons from solar flares (blue) and coronal mass ejections (red). Curved lines illustrate magnetic field lines along which electrons travel from these events toward the Solar Orbiter spacecraft, shown on the right against a starry background. Text explains that more than 300 bursts of 'Solar Energetic Electrons' were observed between November 2020 and December 2022, allowing scientists to connect electrons detected in space with their origins on the Sun.

Our #SolarOrbiter has split the flood of energetic electrons flung out into space from the Sun into two groups, tracing each back to a different kind of outburst from our star 👉 www.esa.int/Science_Expl...

Screenshot of a web search for CDAWeb, giving a website preview with the following text: "April 2, 2025: All SPDF services (CDAWeb, SSCWeb, OMNIWeb, etc.) will be unavailable on Wednesday 4/2/2025 8am - 10am EDT. Please plan your use of the services accordingly."

In case someone else from #heliophysics is wondering why CDAWeb, SSCWeb, or OMNIWeb are not working for them today: There is a planned downtime until 10am EDT.

This is so surreal...

Exactly this. It's as if a lot of people think public transport is only for leisure activities...

👍 I think framadate.org is the perfect replacement for doodle, especially when when2meet is too complicated for some users. 😉

Yes, that's also nice. But I'm not looking for an alternative. Instead I want an *alternative interface* to doodle links that I receive and need to fill out. 🥸

And why is my university actually paying for that service...

I hate filling out doodle.com since it has become so zoomed-in like it wants to be used on a 2'' display... I know that there are alternatives Like when2meet.com, but that doesn't help when replying to requests. Does anyone know if there is some Userscript or alternative interface for doodle.com? 🤔

Given that an initial version of Sharelatex/Overleaf is open source, I'm perplexed that there is not a single competitor around. That's low-hanging fruits! Especially because Overleaf is not really irreplaceable; there is not much data or a follower-base that one wants to keep.

Yes, you're right! I forgot that they squeezed even more, reducing the collaborators to 10 even if you're on a paid plan... I'm a bit ambiguous. On the one hand, they simply offer a good service, so I think it's fine to charge for that. But they're overdoing it, and also in a gatekeeping way.

But I recently took a look at github.com/leouieda/cv and was really impressed what you can do with Tectonic and GitHub nowadays!

While I do see your point, for me the advantage of really being able to simultaneously edit the same part of a latex file with multiple persons outweighs all downsides (so far)... Not to think of instructing other people how to use GitHub for this. 😅

The Indian solar mission #AdityaL1 ☀️ has made their data freely accessible through the ISSDC website. More data will be available following lock in periods.

All versions of Solar-MACH are not working at the moment because #JPL Horizons services are unavailable, possibly due to the #LAFires. Stay safe everyone!

Yep, it's just lovely! And what's best, it runs everywhere I need it: in the terminal, in a Jupyter Notebook, there's even a version for streamlit.

As far as I know, not yet. I think it should become available something like early 2025.

Medium is the Pinterest of written texts: It clutters my search results, and I learned that it's just not worth to click on the link. On my old computer, I had a script that would completely remove those results from the Google search results - maybe it's time to dig something like that up again...

Relativistic electron beams accelerated by an interplanetary shock Collisionless shock waves have long been considered amongst the most prolific particle accelerators in the universe. Shocks alter the plasma they propagate through and often exhibit complex...

Repost from "that place": I. C. Jebaraj's new paper on a relativistic electron beam at an interplanetary shock provides understanding to this phenomenon comparing observations by Solar Orbiter to modelling. arxiv.org/abs/2311.05765

A little update to solar-mach.github.io You can now use single letters to indicate the different spacecraft. Might be faster to recognize them this way, instead of giving them numbers that need to be looked up in the legend! 🙂

I was in the process of writing you a reply when I finally recognized your name and that you're in the same building. 🙈😅 But yeah, not being able to have external people is a huge downside.

We're using a Mattermost (open-source) instance that is run by our university. The only downside is that the server is university-only, so we can't have external collaborators on it...

Nice, and it's not even geo-blocked by ORF! 😊

There's a slow ebb of space-physics folk moving over to this site. I'm going to try and collection new arrivals into a single thread (as there's no lists?), so that we can find each other.

Honestly, I'm not sure. But as it lacks some of the pro features and my uni is paying for the standard Overleaf cloud version, I assume it's the free community edition.

Not sure. Our self-hosted version allows collaboration, but it lacks track changes and requires a university account. So I think one could set it up in a useful way for collaborative work.

Of course, I would prefer a totally community-driven, completely free project, but as long as institutions prefer to buy software & services instead of hiring people to do the job...
