Weirdly, while the site in question is "blaring klaxons!" there are more "cool night lights!" posts than concern.

Unless you're in space, a large scale electrical operator, or relying on HF radio there isn't much reason to be interested other than the lights for a G4 (what this is currently classed as).

Earlier quoted context omitted.

Keep a couple days water and food on hand, go up to the pub, have a pint, and wait for this all to blow over.

With how much modern cars rely on electronics, I would not try to drive during such an event.

Solar flares are only dangerous to very long conductors.

Years 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?

For a really bad event that managed to blow a lot of transformers (presumably due to grid operators not seeing it coming) ... well, take up farming.

We had intense aurora in Berlin, Germany. Green clouds dancing in the sky levels. Started around 22:10 local time or a bit earlier, and at this point there's only a faint red/green glow remaining.

Yeah, there were auroras even as far south as Munich. Maybe not as intense, but it's the first aurora I ever saw, so I can't really judge...

I 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.

Australian Bureau of Meteorology advisory for visible aurora: https://www.sws.bom.gov.au/Aurora

Are there any resources to track Aurora sightings or predicted sightings?

At the bottom right of that page is a subscribe link, with a number of different alerts and lists to subscribe to.

Could you see it from the inner city or only closer to the edges?
