If you go to https://spaceweather.com they have a link for text alerts when these things are about to happen.

That is one way.

I visit that site and a similar site for CME and space weather information: https://www.spaceweatherlive.com

There is a lot to see and to follow. I just came back inside after snapping pics since just after dark here in N Texas. We had a good show that started off behind the clouds but it was bright enough to shine through the clouds. Then a few hours later after the clouds cleared it was great. My camera battery quit on me. I used three cameras tonight and only really got usable photos from my iphone, whose camera I normally hate because it always seems to process images after I take them. Part of it is probably on me since I haven't taken the time to study how to optimize settings.

Anyway. Tomorrow should be another good day for this. Keep your eyes on the sky!

I'd also recommend checking a website like https://www.lightpollutionmap.info to find an area nearby that has less light pollution.

Yes, you can use the NOAA forecast site which will show the "oval" and has 24 hour/30min predictions. Or Space Weather Live has some location forecasts. Generally if you don't live at a high latitude you need a very strong display to see anything. There's usually a bit of warning for storms like this, as various solar observation satellites can beam back images of the CME faster than the solar wind takes to get here.

The keywords to use are “space weather forecast <country>”

I also missed it. Meant to be happening again tonight though.

Tonight at which location? Europe? I might go for a impromptu camping trip!

Apparently much of the Northern Hemisphere, going by how many photos I've seen across the world from last night.

Here in the UK the skies should be clear.
