Folge 10: Die stürmische Seite der Sonne

Achtung! Achtung! Das ist eine Sturmwarnung aus dem Weltall! Ganz so wild geht es im Arbeitsalltag der beiden Astrophysiker:innen Christian Möstl und Hannah Rüdisser zwar nicht (immer) zu, aber sie ha...

Finally, Petra van Lommel taught us how to do space weather communication to the public without scientific terms - use the terms light / rain / wind!
Aurora chaser MaryBeth Kiczenski (photos) provided perspectives for us researchers and forecasters to improve tools to make chases more fun!

Then a discussion with @esa.int and NOAA on future data streams for #spaceweather, with sub-L1 measurements on distant retrograde orbits (ESA HENON and ESA SHIELD) attracting lots of attention. An ESA L3 mission concept may use Faraday rotation to remotely detect #solarstorm magnetic fields. (2/3)

Day 4 of #ESWW2025! @maikebauer.bsky.social + @lelouedecj.bsky.social presented posters on #solarstorm automatic detection and modeling to make life easier for forecasters. @hannahruedisser.bsky.social took part in a panel on the best practices and future use of AI in #spaceweather! 1/3

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 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)👇

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. ☀️💥🤖

Maria Federica Marcucci on the @esa.int M7 mission candidate "Plasma observatory", which would be an amazing mission to understand in high detail how the solar wind works on small scales and how it interacts with the 🌍 magnetosphere.

🇬🇧UK Space Weather meeting in Sheffield, day 3 starts with a session on new 🛰️ missions, including @craig.deforest.org on @punch-mission.bsky.social, Jorge Amaya on a new fleet of @esa.int spacecraft and a possible later far-side ☀️ mission (near L3), and Jonathan Eastwood on ESA HENON for sub-L1 data.

Some impressions from the UK 🇬🇧💂‍♂️ Space Weather and
Space Environment Meeting III in Sheffield this week - I talked about research to operations to research at @aswogeosphere.bsky.social and the usage for spacecraft measuring solar storm magnetic fields closer to the Sun ☀️ (so called sub-L1 monitors).

This #solarstorm from late Aug 30 2025 will arrive at 🌍 noon to late Monday Sep 1.
Depending on its internal magnetic field, it has the potential for #aurora in central Europe and maybe #GNSS errors.
Parker Solar Probe will tell us in hindsight if its field was predictable from 0.5 au.

The new AI foundation-type model, based on Solar Dynamics Observatory data, arxiv.org/abs/2508.141...
is also featured @wired.com

IBM and NASA Develop a Digital Twin of the Sun to Predict Future Solar Storms

The tool models the sun using AI, and its developers say it can anticipate solar flares 16 percent more accurately and in half the time of current prediction systems.

Sure, but I would not worry about any of those systems crossing that threshold. Its just weird that the whole thing is framed as a „race towards AGI“ while we in the end we get a lot of useful tools but nothing near those promises.

Of course this is meant with regards to large language models (LLMs). Deep learning (DL) is e.g. highly useful for things line automatic detection of structures, as pattern recognition was for long time a particular strength of humans, and DL is catching up and surpassing humans for large datasets.

This is a really great summary of the current state of #AI.
For my scientific work 🧑‍💻 its useful to (1) quickly summarize fields that I am not familiar with and (2) to give me templates for coding.
Both are great tools ⚒️ but a far cry from AGI/ASI.

WELCOME TO THE FAMILY, ALPHA CEN A b!!!

First hinted at in Wagner+21, now Chas Beichman, Aniket Sanghi and team have published new JWST images of alpha Cen A showing another hint of this Saturn-sized planet candidate!

This years @erc.europa.eu Advanced Grant results are out! In solar system sciences and #heliophysics there are projects on solar coronal heating, stellar convection and icy moons.
Otherwise in #astrophysics topics like planet formation, black holes and dark matter were selected.

European Research Council (ERC) @erc.europa.eu · Jun 17

Some moons 🌕 orbiting Jupiter and Saturn 🪐 host vast oceans 🌊 buried beneath kilometres of ice 🧊.

These hidden seas are promising environments for hosting extraterrestrial life!

Stéphanie Cazaux will investigate them 👉 buff.ly/JIILCVU

What a week for #heliophysics 🔥: first #solarstorm imaged with NASA @punch-mission.bsky.social, @esa.int Solar Orbiter provides the first view of the solar south pole, and @esa.int Proba-3 demonstrates formation flying and imaging the inner solar corona.

Breaking space news: We have made our own solar eclipse in space! 🌘

Today, we release the first images from our Proba-3 mission, which flies two spacecraft in precise formation to create artificial solar eclipses in orbit.

Highly fascinating that for the @esa.int gravitational wave observatory #LISA (launch ~2035), #spaceweather effects need to be studied. Kind of logical, due to the superhigh sensitivity of the observations. 2035 is the max of solar cycle 26, and we might know its strength in the early 2030s.

I am not involved in this! Nils Janitzek gave an introduction yesterday in the Solar Orbiter working groups meeting.
