If anyone is interested in what "G4" means in context, here's the scale: https://www.swpc.noaa.gov/noaa-scales-explanation
This was an S4 event, however.

G4: " Induced pipeline currents affect preventive measures, HF radio propagation sporadic..." G5: " Pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days..."
Waiting until it's like a G6, Like a G6 Now I'm feelin' so fly like a G6
Thanks, really had to listen to the song.

#133How rare is this? G4 storms are ~100 per solar cycle (~11 years). So roughly 9 G4 events/year on average.
This is an S4, though.
Re: Level S4 solar radiation event
#134I missed it (seeing the Aurora) .. are there any reliable alerts for this sort of event, that do not alert me about anything else, but really only such big events?

Could you see it from the inner city or only closer to the edges?
Friends who live in Kreuzberg and Friedrichshain could see it pretty well. I'm a bit further south within Berlin where skies are minimally darker, but between 10pm and 11pm it was so bright that light pollution didn't matter. Funnily enough, despite having lots of alerts set up it was my mom who texted me from northern Brandenburg as she spotted it after getting an alert from RegenRadar, of all apps...
Saw it in Fhain as well over Ostkreuz station

#139I'll be going out tonight if this continues into Australian night time hours. At this strength, I could see the full display including colors with my naked eye in Melbourne, May 11th 2024. This storm is slightly stronger than that event.
I'll be attempting to get some photos/footage from Esperance.
Re: Level S4 solar radiation event
#140I live somewhat close to the arctic circle and the aurora has been exceptional lately. One recent evening it looked like there was a massive city behind the cloud cover, and a few nights before when the sky was clear I watched enormous green flames for hours.
