Here are a few quotes by @chrisoutofspace.bsky.social in the Austrian newspaper @derstandard.at on the Sivadas et al. paper: www.derstandard.at/story/300000...

Sonnenstürme sind offenbar gefährlicher als gedacht

Einer aktuellen Studie zufolge wird das Risiko von geomagnetischen Stürmen, die etwa Blackouts verursachen können, unterschätzt. Schuld daran ist eine statistische Illusion

China's Tianwen-2 has first imaged asteroid Kamoʻoalewa, which is on a wide orbit around Earth 🌍 between 0.9 and 1.1 au, but tilted to the ecliptic by 8°. This is close to "distant retrograde orbits" for future space weather forecasting missions like @esa.int HENON. www.youtube.com/watch?v=SbbA...

We had an amazing time at #solarwind17 in Bath / UK, learning about current solar wind science on all scales and presenting our work on solar storm forecasting and multispacecraft observations of their evolution. Plus a visit of Stonehenge and World Cup wins for England and Austria!

At the #SolarWind17 conference in Bath UK this week (after going through London Paddington station) - first sessions about solar wind small-scale physics and turbulence, and a tutorial on getting funding from the @erc.europa.eu!

Looking at the recent #solarstorms that are expected to arrive at Earth 🌍 around late Thu June 4 (from early June 3), I am quite skeptical on their geomagnetic storm potential. The flares were of short duration, there are no clear halo CMEs and all eruptions a going mainly to north/south in LASCO.

Fun and productive week @issibern.ch with an ISSI team working on the connection between heliospheric and magnetospheric data and models for improved #spaceweather forecasts. Bonus: the @science.esa.int launch of SMILE 🚀! teams.issibern.ch/space-weathe...

Great that the @esa.int SMILE launch went so smooth, looking forward to the new images of the magnetopause and aurora! Always good to have another in situ monitor near Earth. I got to shortly comment on the technological effects of #spaceweather on Austrian national TV: on.orf.at/live?channel...

Impressions from the @esa.int heliophysics modeling workshop this week at ESOC in Darmstadt - amazing to see a roundup of the #spaceweather modeling landscape, as well as the ESOC control rooms, and even a Rosetta/Philae spacecraft model in real size!

The #solarstorm from March 30 has gone way off to the east of Earth (solar wind, left), so no problem for #ARTEMIS2. Fingers crossed🤞that during the 10 day journey to the moon a solar energetic particle (SEP) hazard does not occur - see data on the Jan 19 2026 event by the LRO spacecraft👇(right).

We've been featured on Austrian national TV ORF2 in "Mayrs Magazin" roaming around Austria's magnetic Conrad observatory and talking about solar storms, with @chrisoutofspace.bsky.social and Veronika Haberle. The @esa.int HENON and Vigil missions were mentioned too! on.orf.at/video/143147...

spaceweather.com sometimes posts solar images from the #Mars Perseverance Rover camera MASTCAM-Z, in low but good enough resolution to see big sunspots (e.g. Feb 19 2026 below). Mars is currently on the opposite side of the Sun as seen from Earth. The images are here: mars.nasa.gov/mars2020/mul...

BREAKING: This is Richard Carrington, the first person to document solar flares on the Sun & suggest their influence on aurora at Earth. The largest solar storm on record, the Carrington Event, bares his name. But, there has been no photograph available of Carrington – until now!

We are situated in Graz #Austria and this is the view from the Schöckl mountain on Jan 19 2026 23:00 CEST. #spaceweather #aurora #polarlights

This solar cycle is so funny because whenever you think you don't know exactly what to do for the next paper or project these things happen.

Wow! Here is the current view over Falkenberg, Germany! Quite amazing red aurora from this mid-latitude location. Europe get outside! go.theauroraguy.com/webcams

This is likely the strongest near-Earth #solarwind magnetic field I have ever seen in my career - 90.6 nT total field, and perfectly northward 61.7 nT Bz component. If this is the main flux rope, the north and west pointing field is consistent with the right handed source region - Bz would stay > 0!

A press story is out today (german) on our forecast for the chances for #aurora nights at mid-latitudes in 2026. We predict another 1-2 possible nights in 2026, as we expect 20-30 #solarstorm impacts at Earth 🌍 in 2026. ☀️ Solar cycle 25 is not done yet! ☀️ science.apa.at/power-search...

My take away so far from discussions on the #Airbus software updates due to potential #spaceweather induced electronics upsets: the Sun ☀️ seems not responsible for the incident on October 30 (no significant eruptions on that day), but solar energetic particles could lead to similar failures.

An interesting #spaceweather story developing. Airbus has made a statement saying that “Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls” www.bbc.co.uk/news/article...

Flights disrupted as Airbus requests modifications to thousands of planes

About 6,000 plans are thought to be affected, about half the European aerospace giant's global fleet.

We will hear more details in the coming days but it also looks like ESA Space Safety - with a highly ambitious program - was very well funded, and besides the Asteroid mission to Apophis in 2029 (once in a lifetime chance), eager to hear more about the #spacewather missions to be designed and built!
