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 ⏱️

☀️ 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

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. ☀️💥🤖

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 👇

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...

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