Another article completely overselling the importance of geomagnetic storms for orbital lifetime and downplaying the lesser known but much more important solar EUV variability.

Let’s make today (May 10) Magnetosphere Appreciation Day! A year ago today we had that huge aurora display, caused by the most powerful geomagnetic storm experienced in decades. Lovely visualisations by NASA SVS/NASA DRIVE science centre on how our atmosphere and magnetosphere responded. 🧪🔭☀️🧲

NY Times links to a ROSCOSMOS Telegram message, citing a 6:24 reentry west of Middle Andaman Island, based on their calculations. Observations are not mentioned, so I think we still need to interpret this with some residual uncertainty. www.nytimes.com/2025/05/10/s...

NASA just released the first-light images from the PUNCH mission! The WFI images are spectacular. More images will be forthcoming on the PUNCH website soon. 🔭🛰️☀️

Spectacular looking eruption. However, it was more E than NE. This source of the SUVI images does not put north up, for some reason. That plays a role for assessing the probability of a geomagnetic storm in case this region continues to erupt.

Uitbarstingen op de zon kunnen onze infrastructuur raken. Dankzij herontdekte magnetismemetingen uit 1859 kan het KNMI nu beter inschatten wat de impact zou zijn van extreem ruimteweer. 🔗 www.knmi.nl/over-het-knm...

PUNCH is orbiting and all four spacecraft are Sun-pointed. I can sleep now. ☀️🛰️🔭🚀

While we are in a bit of a CME drought right now, worry not, the Sun is still active. Look at this incredible filament eruption yesterday near the Sun's eastern limb. This CME is not directed at Earth, but it looked spectacular in EUV imagery. #heliophysics

The Severe Geomagnetic Storm of October 2024
The G4 SEVERE geomagnetic storm of October 2024 created stunning auroral displays. Find out why it was unique and how you can predict the aurora next time!

I've created some summary plots of space weather in 2024 for a publication of our institute looking back on last year. These are the English language versions. In the flare plot, the largest flare for each month is labeled.

The survey locations from this paper are also available in these timeline viewer layouts. spaceweather.knmi.nl/viewer/?layo... and spaceweather.knmi.nl/viewer/?layo... Thanks to the authors for making this dataset available. I look forward to further work making combinations of datasets more useful.

The two slow eruptions of last Tuesday can be nicely tracked from GOES SUVI 304Å to SOHO LASCO C2. They are followed by the very fast far-side halo CME, which was not visible in SUVI 304Å, only in LASCO. Using jHelioviewer.

Very interesting Veritasium movie about Amelia Earhart's last flight, with some great info about 1930s radio navigation methods, mentioning the frequency-dependent role of the ionosphere. Highly recommended! bsky.app/profile/veri...

I'm starting to dive into the ionosphere data from Android phones published last week in Nature: doi.org/10.1038/s415.... Browsing through the contents behind the paper's data link (doi.org/10.24433/CO.... - play the video). This is a rich dataset for ionospheric research!
