I will post detailed how-to scripts next week, to download, process and use these images!
I got it to work for 2 years of data and it seems rather stable ^^'

Agreed, most of the reduction code in IDL was hard to wrap my head around!

Lasco C2 running difference

COR2 running difference

Been working on converting coronagraph IDL routines for Lasco C2 and C3 + STEREO COR2 to Python.
Most of it is working and produces nice coronagraphs, might be some bugs and missing features, but you can find it here: github.com/lelouedec/He...

Happy Holidays from the team of the Austrian Space Weather Office at the GeoSphere Austria!

Another #solarstorm is approaching Earth 🌍 It's associated with an X1.2-class solar flare, again from active region AR 14274 (same as the CME predicted to arrive late tomorrow). It has an estimated initial speed of 1208 km/s - expected arrival is Wednesday, November 12th around 02:47 ± 5.67 UTC.

Another fast CME (speed around 840 km/s) is expected to arrive at Earth around 04:33 ± 6.25 UTC on Friday, November 7th ⏱️

Three plots showing current space weather conditions at Earth. The left-most plot shows the magentic field conditions, with a currently positive Bz component that was previously negative. The middle plot shows the Dst index, which currently sits at around -110 nT. The right-most plot shows the Newell coupling, which is currently at close to 0, but has peaked around 4.

☀️ Earth is currently experiencing a class G3 geomagnetic storm (likely caused by a #solarstorm flank hit), with Dst values going as low as -136 nT in the last 12 hours. Bz magnetic field component is currently positive, Dst values remain around -110 nT

Quite the uncertainty

Day 3 at #ESWW2025! @hannahruedisser.bsky.social presented our automatic solar storm detection method ARCANE, combined with our models for the storm magnetic field (3DCORE) and arrival time (ELEvo), showcasing their power for real time application. (1/2)👇

ARCANE with its ability to also detect high speed solar wind streams was also shown during the live #spaceweather forecast!
Further, fascinating talks on geomagnetically induced currents in Sweden, Germany and New Zealand, and discussions on ESA space weather plans for the next few years. (2/2)

Day 2 at #ESWW2025! @spacedavies.bsky.social rocked the stage with a talk on solar storm forecasts with sub-L1 monitors with @esa.int #SolarOrbiter. I participated in 2 panel discussion, on the role of validation, and the future of space weather modeling at ESA in the next 10-15 years. ☀️💥🤖

Pairs well with Parmegiano and grape juice!

Happy Holidays from the Austrian Space Weather Office!
2024 featured the 2 strongest #solarstorm impacts at 🌍 in 20 years, and we could heavily improve our approach of combining research and operations in #spaceweather.
On to another year of solar cycle maximum in 2025!
Our achievements in 2024 👇

Best book to get introduced to the sun and its wonders :)

EGU2025 and space weather news! 🤖 🌞
We are organising the "Machine Learning in Planetary Sciences and Heliophysics" session at the upcoming European Geosciences Union (EGU) in April 2025, together with @hannahruedisser.bsky.social and GautierNguyen.

De-noising and cadence interpolation ✅ (hopefully preprint soon)
Data gaps: 💀
We really need more bandwidth for forecasting purposes, or ways to compensate for missing frames

First post on there, so comparing Beacon to Science data of STEREOA of course.
