Nice, you can already see some solar flares in Austria again. https://www.foto-webcam.eu/webcam/kleinfleisskees/ https://www.foto-webcam.eu/
Those images around 19:00 are amazing. Thanks for sharing.

#42I wonder if we're going to see an aurora over Seattle tonight?
Re: Level S4 solar radiation event
#43Years ago I was concerned about this and made a plan with my wife for what to do if she was at work. But now we have a bunch of kids in different schools and haven't updated our plan. Does anyone have a plan for what happens if we have a really bad event?
Buy a bit of extra food and water.
And toilet paper! Rolls and rolls of toilet paper!

#44We never get aurora in Japan :(

#45This page looks like an accessibility nightmare. The entire warning text is an image. There is no transcription present for screen reader users. I did not expect this from a government website.
Re: Level S4 solar radiation event
#46Do you need long exposure to make it visible with a camera? How does that work in the presence of light pollution?
Local light pollution normally makes it hard to see with anything short of long exposure, but today it was naked eye visible and regular photos also captured it.

#47If anyone is interested in what "G4" means in context, here's the scale: https://www.swpc.noaa.gov/noaa-scales-explanation
Looks like we get these for about 60 days for periods lasting 11 years.

#48I had the most intensely coloured lights visible in the west of Ireland. I've seen them a few times before but never like this. Phones were capturing them in video not just long exposures. Not sure what the best service is to be alerted ahead of time. Apparently it'll be strong here again at 6am according to some of the apps some random people were waving around.
There are several apps that do a good job of alerting users. I use "Aurora Pro", which I prefer because it checks cloud cover and lets you set alert thresholds based on viewing probability.

#49How rare is this?
G4 storms are ~100 per solar cycle (~11 years).
So roughly 9 G4 events/year on average.

I woke up to a notification from aurora pro today, I'd forgotten I had the app. This would explain it
