Seeing all these aurora pics from Europe...
Damn, this storm is evolving fast. I can't keep up with everything. Auroral index is through the roof. GOES spacecraft are outside the magnetosphere (and scared, prolly).
I can't keep up with the great people posting info in real time!!

Space weather storm is here! ...EARLY! This is a good sign for mid-latitude aurora.
Unfortunately, real time solar wind data is giving erroneous velocity data (a near constant 300 km/s). We'll pay attention to density and magnetic field to see how this unfolds.

This was super cool to watch, especially the concluding message at the end about American cities.

I love Detroit; my parents are from the city and it's part of my heritage. I have been lucky to do a lot of fun things in the city as of late.

#AGU25 this week has been a joyful and grim time. It's great to see colleagues and friends, and the meeting is always overwhelmingly productive. However, we continue to learn about the depths to which the current administration is attempting to dismantle science.

I entirely agree with Eric's second point: the space community has been suffering from the lack of stable leadership at NASA. [cont'd]

This storm is highlighting our lack of capability. Our two spacecraft capable of real-time solar wind monitoring are struggling. ACE's plasma detector is giving clearly WRONG data, while DSCOVR is known to give unreliable values.
SWFO, hurry up!

This looks like it could be a big one! Look to the skies this evening.... But now that I've said that, I've jinxed it.

Scoop: Trump has started demolishing the White House's East Wing facade to build his ballroom. The president had claimed construction of the $250 million building wouldn’t ‘interfere’ with the existing White House structure. /W @ddiamond.bsky.social wapo.st/4hqBNiU

Find a No Kings protest Saturday and go!
Don't worry that you've never been to a protest before. Don't worry about being dressed wrong or looking out of place. Don't worry that you don't agree about everything -- or even about much -- with lots of people at the protest.
