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.

#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

Congratulations, Hannah!!! 🤩 @hannahruedisser.bsky.social

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. 🧪🚀🛰️🔭☀️ punch.space.swri.edu/punch_scienc...

Some impressions from day one at #ESWW2025 including first poster presentations and big congrats to long-time collaborator Erika Palmerio @erikapal.bsky.social for receiving the Alexander Chizhevsky Medal for early career scientists!

👏 to our Satabdwa Majumdar @satabdwa.bsky.social who had an invited talk about solar wind modeling at a conference in India!

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. @aseastronauts.bsky.social @fwf-at.bsky.social

This event was somehow annoying 😅 #heliophysics

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!

☀️ Possible Aurora in Austria this evening (solar storm has not arrived yet) ☀️

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. 👇

Academia may not give you job security, flexibility, or wealth, but it will let you unexpectedly connect to eduroam in foreign cities

Over the weekend our story on new papers on AI 🤖usage for improving #solarstorm ☀️💨 images and their detection by @maikebauer.bsky.social and @lelouedecj.bsky.social has been featured on national Austrian TV (ORF2) and radio (Ö1) (both german) TV on.orf.at/video/142878...

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. ☀️ www.geosphere.at/en/news-and-...

Dringender Aufruf zum Blutspenden in #Graz Ab 16:00 im Jugend- und Familiengästehaus in der Idlhofgasse!

In the last 2 weeks @tamersto.bsky.social, Ute Amerstorfer, @chrisoutofspace.bsky.social and Maike Bauer (online) participated in 2 teams at @issibern.ch to work on 3D reconstructions of #solarstorms, and to improve #spaceweather forecasting from a combined heliospheric and magnetospheric view. ☀️

Check out my recent paper, just published in ApJ! ☄️

We have updated spacecraft mission trajectory movies for @esa.int Solar Orbiter, BepiColombo and NASA Parker Solar Probe, for the whole decade 2020 to 2030. There are extra movies for 2025-2030 for the just launched #PUNCH mission, for context where the other spacecraft are. doi.org/10.6084/m9.f...

☀️ We have a new paper out—work led by @drbjl.bsky.social: We analysed a simulated CME via synthetic (remote-sensing and in-situ) observations, incl. Parker Solar Probe-like encounters close to 10 Rs and WISPR imaging. We reproduced many features found in real data. ApJS link: doi.org/10.3847/1538...

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. meetingorganizer.copernicus.org/EGU25/sessio...

Traditionally after the holiday break, abstracts for the EGU 2025 in Vienna are due on Wed Jan 15. We are (co-)convening 3 sessions on #spaceweather and #heliophysics! @eurogeosciences.bsky.social @lelouedecj.bsky.social @maikebauer.bsky.social @hannahruedisser.bsky.social @spacedavies.bsky.social

As the geomagnetic storm is subsiding, some more super nice #aurora pictures from Hubert Krapfl from Austria (Styria, oberes Murtal), 2025 Jan 1 18:40 CET.

Central Europe, if there are no clouds in your area, watch out for #aurora tonight! The 4th strongest geomagnetic storm in cycle 25 as measured by Dst is ongoing and likely persisting into the night. A #solarstorm magnetic rope with a very favorable west-south-east configuration sweeps over Earth.

Merry Christmas to all of you! ☀️

Two very photogenic eruptions of plasma from the eastern edge of the Sun this morning! Neither are Earth-directed. (Observations from the GOES/SUVI instrument). #spaceweather

Treat yourself by watching this loop for a while. A close-up of the surface of Comet 67P/Churyumov-Gerasimenko, seen by the Rosetta spacecraft's OSIRIS camera in 2016 and processed by @landru79.bsky.social. The "snow" is actually dust particles... in front of a moving ocean of stars.

Happy #ionosphere discovery day everybody! On this day in 1924, Edward Appleton conducted a neat experiment to prove the existence of a radio-reflecting layer in the Earth's upper atmosphere. To celebrate, I did a thing. You can watch it here; youtu.be/JWop2aGKKSE

Please consider submitting an abstract or sharing the call with your network. 📢 🔍 Topics include: - ML/deep learning in space research and heliophysics - Novel datasets and statistical analysis methods - Fusion of learning-based and physics-based model

Reminder to submit your abstract to our session at EGU. If you plan to ask for financial support, you have until the 12th of December to submit your abstract!

👇We have now switched fully to bluesky!

Hello there, our team at the Austrian Space Weather Office at the GeoSphere Austria will continue here to post infos on solar eruptions as they happen in real time ☀️🌬️🌍, as well as on our research to improve our understanding of #heliophysics and #space weather!
