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! 🙂

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...

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...

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? 🤔

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!

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...

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.
