Eelco Doornbos @eelcodoornbos.bsky.social · 12/06/2025Another article completely overselling the importance of geomagnetic storms for orbital lifetime and downplaying the lesser known but much more important solar EUV variability. 1110

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. 🧪🔭☀️🧲 19470124
Eelco Doornbos @eelcodoornbos.bsky.social · 10/05/2025NY 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... 000

Eelco Doornbos @eelcodoornbos.bsky.social · 29/03/2025Spectacular 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. 030

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 619524

Eelco Doornbos @eelcodoornbos.bsky.social · 19/12/2024The 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. 010
