#2If you have a pair of eclipse glasses you may be able to see the sunspot cluster causing all the action with them, it’s enormous.

#4I'm quite worried as I'm on a transatlantic flight during this event, and there have been 6 solar eruptions with at least 4 CMEs (NOAA not up to date with the enlil spiral just yet). Here are a couple useful links I'm using to keep track of this event: NOAA Space Weather Prediction Center dashboards [1], FlightAware Flight Delays and Cancellations [2] and NOAA Global Positioning System Community Dashboard [3], Prof. Mathew Owens post [4]

#6I am confused by the slide, which mentions in the first bullet point that this is the first "G4" since 2005, but in the last bullet point says there was one in March.

It’s the first G4 watch, but not the first G4 event. In other words, the prior G4 event was not predicted. It can happen that an event is more significant when it arrives than what was predicted, which is what happened here.

it's a typo, Mar 2024 was a G3, not G4. ref https://news.ycombinator.com/item?id=39796973 and link in comments there.
[edit] i stand corrected, there was a G4 in march. sibling comment is correct. ref https://www.swpc.noaa.gov/news/severe-g4-geomagnetic-storms-...
