🚀 Excited to share that after my time as Associate Editor, I've been promoted to Editor at AGU Space Weather.

I'm really grateful for the opportunity to support space weather research and work with authors, reviewers, and the editorial team to help advance the community. ☀️

Hannah T. Rüdisser @hannahruedisser.bsky.social represented the Austrian Space Weather Office and GeoSphere Austria at the Exner medal lecture for Sepp Hochreiter @hochreitersepp.bsky.social in Vienna yesterday, talking about the usage of AI in #spaceweather!

Here is todays Nov 14 #solarstorm (NOT Earth directed 🙃) in its full glory - it has one super interesting feature concerning future #spaceweather missions!
Guess which 🤔
First the solar source as imaged in extreme ultraviolet by NASA/SDO:

A shock arrived Nov 12 7:32 UT at Solar Orbiter, from the early Tue Nov 11 X5 flare #solarstorm. Reminder: SolO is at 17.5° east, 10.3° north of Earth, 0.83 au, so our forecast should be taken with a grain of salt as its quite a bit away from the Sun Earth-line - it will not fully match L1 data.

The #northernlights were also seen at the Sonnblick Observatory from the GeoSphere Austria early on Nov 12 2025!

Resulting in a massive maximum total magnetic field of 63 nT, presumably the #solarstorm from Monday morning arrived 2025 Nov 11 23:38 at L1, and interacted with the previous storm just before it arrived at the L1 point near Earth. Dst reached - 238 nT, which is the 3rd strongest storm of this cycle

We are waiting for the arrival of both #solarstorms at the @esa.int #SolarOrbiter spacecraft. Its magnetometer could measure their internal magnetic field which can improve our forecasts. It is a bit away from the Sun-Earth line at 10° north / 18° west but at a good distance of 0.83 au from the ☀️

The source region of both #solarstorms, one from early Sunday Nov 9, and the other from early Monday Nov 10, are (as usual) complex. Judging from the main neutral line, where the +/white, and -/black magnetic fields meet, we may expect a magnetic field rotation as south-east-north (SEN) or ENW.

Three plots, stacked vertically, showing measured quantities related to the solar wind at L1. The top panel shows the magnetic field, with separate colors indicating the differend field components, the middle panel shows the solar wind speed, and the bottom panel shows the density.

#solarstorm update 💥 - the CME predicted to arrive early Friday, November 7th seems to have impacted L1 around 04:51 UTC today - speed around 793 km/s, Bz initially northward with strength around 13 nT and currently at -7 nT

We just rolled out v0h of the PUNCH data pipeline. Most of Aug and Sep are now up. By Sunday we should have reprocessed it all. The L2 data include 4-min-cadence images of 3I/Atlas for those who wish to verify it is not an alien spaceship doing maneuvers. 🧪🚀🛰️🔭☀️

There are a few rather minor #solarstorms traveling to the west of Earth at the moment, and we expect only minor effects at Earth in the next few days, starting Thursday October 16. Likely only high-latitude #aurora is possible.
However - the @esa.int #SolarOrbiter spacecraft observed them!

#ThisWeek in 1991! On 2 October, Franz Viehböck became Austria's first astronaut. He was launched on Soyuz TM-13 to the Mir space station with colleagues Toktar Aubakirov and Alexander Volkov, returning on Soyuz TM-12 after just over a week in space.

Storm update: A flux rope arrived at 10:20 UTC, raising the magnetic field strength to currently 23 nT. For now, Bz remains positive.
Rooting for a low-inclination, left-handed flux rope — that could flip Bz southward and boost #aurora chances again! ✨🤞 Stay tuned!

This cluster of ☀️ active regions, with sunspots showing magnetic fields in the SDO image on the left, is rotating towards Earth 🌍 in the coming week.
While the sunspot number (from SIDC Belgium, right image) made a dip in the last few months, some elevated solar activity could now be coming up. 👇

Artificial intelligence improves the prediction of solar storms Two new scientific studies by GeoSphere Austria provide important contributions to the analysis and prediction of space weather.

Proud of our project results achieved by @maikebauer.bsky.social and @lelouedecj.bsky.social 🤩

Following the evolution of solar storms in heliospheric images can now be done automatically using AI. ☀️
