This is why we need continuity of measurements,overlap and redundancy of measurements across different locations! The answer has real world implications for how we run and train models and understand how storms arrive at Earth from the sun!

Shocking contrast between the solar wind density values observed by IMAP versus ACE- as much as 20 times higher in the new IMAP versus the very old ACE!!!
We know ACE is getting old, but holy smokes that's a staggering difference.

ICE murdered Renée Good in broad daylight. Less than 3 weeks later, they killed Alex Pretti, shooting him 10 times. Every day, we watch as people are ripped from their cars, their homes, their lives.
We can't allow ourselves to look away from this cruelty. Abolish ICE.

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.

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!
