He/Him. Prof. at the University of Michigan's Climate and Space department. Space scientist. Connoisseur of dumb humor. Opinions and stupid jokes are my own.
Ah, we'll catch you in the playoffs. 😉😁🤪 ggwp. Go loins.

The hope is that Space Weather Follow-On (SWFO), currently on it's way to the first Lagrange point (L1), will solve this observational/operational crisis. SWFO was designed from the ground-up for operations- it should give some *excellent* data.

So what does SWPC do? They switch to DSCOVR! DSCOVR's plasma instrument is also suspect, often yielding WILD oscillations that are not accurate. That's happening right now! See my annotations in the plot below. You can see when SWPC switches to DSCOVR and when DSCOVR goes nuts.

...breaking this down: this is ACE real time data. The plasma instrument, SWEPAM, is very old. Under strong conditions, the instrument can not give good, clean data. We can see the precise moment where SWEPAM stops operating accurately in the orange, yellow, and green lines below.

This storm is nuts! Nuts, I tell you!

I love that. Looks just like me.
Why's he sound like that?

Phew... where do we start. ST miscues (big returns, blocked FG). Goff inaccurate early. Passpro is not good enough; interior run blocking not good. D was okay, but missed tackles sprinkled about. LOTS of penalties and miscues. Team wasn't ready AT ALL.

Two other effects highlighted in this talk:

1) Sat electrical discharges are strong enough to be measured on the ground (!!!)
2) Sat flybys are detectable electromagnetically.

Overall message: space is becoming more polluted, and we need to come to terms with that.

Ah, yes- the Earth's well known... uh... quadrupole magnetic field.
