I barely passed freshman physics. I had literally no idea what real physics was, what profs did, or what research was at the time. 18 yo me thought the classes were just a legalized irrelevant form of torture. Undergrad research & mentoring opened my 👀, thanks @nasa scholarship!

Got home with some nasty AGU COVID, my 1st case. The science was great but the health risks are so large and unmitigated and normalized, I have very mixed feelings. Basically scientists are condoning a super spreader is what it feels like. I tried to mask but did not do enough.

@KateClancy uggggg.... there should be levels for how bad these get. Metrics maybe. If they reach a certain level, they have to pay more for your self-care. Stickers you can give out that say 'I mean well but I am part of the problem'. Or maybe stickers with a secret color code... ???🤨

Continuing on the technical terms, ;) the main phase of this storm (according to the real-time Dst) is -231 nT. Nearly superstorm level (-250 nT) and not seen for *many* years I believe. read more about red aurora here:

Mother forking shirtballs, it's really kicking off at STEREO-A (which is a few hours ahead of Earth, in solar wind terms.) Total field ~80nT, with a lot of that southward, maybe -75 nT?!. This is going to be big when it reaches Earth.

PSA for #AGU18 conveners: if your session has 25% women, your oral session should not have 1 woman out of 9 talks! 🤯 I🧡 that I can cite @theAGU 's diversity policy to fix this. #implicitbias

Absolutely fascinating talk #ESWW15 by Delores Knipp on the 1972 Carrington-like storm that actually exploded 25 US Navy mines in the Haifong Sea. Big mystery, Dst was only -125 nT for this storm, but the mines were sensitive to dB/dt (a big fast change in magnetic field). 🧲🧭💣

@_Astro_Nerd_ Serious answer, someone who listens, inspires, and has vision for you even when you don't know where to go because they share their experience. More formally, you might like to check out the book "The Mentee's Guide", or this older free version:

What's happening in the sky this unusual night? Most striking in the featured 4.5-hour 360-degree panoramic video, perhaps, is the pink and purple aurora. That's because this night, encompassing May 11, was famous for its auroral skies around the world. As the night progresses,

23.43º — that's the angle of Earth's axial tilt compared to the plane of its orbit around the Sun and why we have seasons.

So where is the #starman right now? We have some good real time estimates for what/where/how strong the radiation belts are from the Van Allen Probes measurements... Gonna check them out & share.

-268 nT and still dropping like a rock. I've seen solar wind going 800 km/s before, but don't think I've ever personally seen this strong of B fields (60 nT) in the solar wind near-Earth data!

Sigh, it should not take two female experts (with 40 years of experience between them) 3 tries and a video telecon to correct one dude (with less than 1 year of experience) out of his misunderstanding of their instrument... And sadly, that is one of the more self-aware 🛰️ dudes.

Amazing finale talk #cswglobal18 @carrieseltzer . So many similarities between @inaturalist & @TweetAurora . A great Q from Orin @HorizonState : how can diverse platforms be horizontally integrated? Yes, very important for the future, & very difficult at current project scales.

🤩 as a mere space plasma physicist and dark matter skeptic I really enjoyed @skdh 's cool video on the topic's recent status... and I still submit quietly that plasma physicists need to be in the loop to help breakthrough the universe's invisible quagmires
