Used to use a NOAA page, but they changed it a while ago and don't find it as useful anymore. https://www.swpc.noaa.gov/communities/aurora-dashboard-exper...
Some weather services also have a kp index, but I often feel those can't be trusted, and don't tell the whole story. And aurora is quite hit or miss, so need more updated data.
I have an app on my phone (AuroraNotifier) that chimes when there's hope. And then I use these others to plan a bit better. But some more interactive map akin to the uit.no one but where I can place myself around would be nice.
Edit: someone posted this below, looks nice, have some other kinds of data https://www.spaceweatherlive.com/en.html
