We never get aurora in Japan :(
Hokkaido got some back in November: https://www.asahi.com/ajw/articles/16155623

#163Our network router in our radio station started acting crazy at 22:00:40 Europe/Ljubljana time. Uptime monitoring via HTTPS reported downtime for 5 minutes, but our radio archive that records audio over LiveWire recorded some bitcrushing effects for 5 minues. Maybe our Mikrotik hEX was flipping some bits? Recording from the radio archive: https://splet.4a.si./dir/solar.mp3
Re: Level S4 solar radiation event
#164I 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?
On iOS there’s an app literally called “Aurora”.
It will notify you when you’re in an area with a high Kp (or above a Kp you specify).

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..."
"Free Energy!"
I wonder if they’re still putting out music …

Yes, sounds similar to a corrupted digital audio.
Replace hex with something more robust, at least with an actual metallic case.

One caveat is, that these events cannot be forecasted in the same way as weather on earth can. You usually only have a lead time of 15 - 45 minutes. See also https://www.swpc.noaa.gov/content/aurora-tutorial
Sure. But if I am awake, those 15 minutes are enough to get dressed and go outside. Yesterday I just would have had to walk to the balkony to see it, but I was busy with some frustrating coding problem instead ..
same, I was awake for the whole night but completely missed it

That’s beautiful. But you get aurora even sans G4, true? Was this more intense and spectacular?

Possibly the most brilliant are around: - https://www.foto-webcam.eu/webcam/ederplan/2026/01/19/2230 - https://www.foto-webcam.eu/webcam/ederplan/2026/01/19/2240 Incredible, thanks so much!
Crazy how many starlink satellite trains can be seen here. I spotted 4 trains, in that one cam
Isn't that just 4 sats and it looks like that because of long exposure?
