We’ve had plenty of solar activity in the past week, and the POES site has been down for maintenance. What frustrating timing!
So this morning I did some searching for more aurora maps, thinking maybe I’d find an ESA one or something. Well, I didn’t find a direct substitute for POES, but I did find OVATION.
On the one hand, I don’t think its the same data set as POES (I can’t actually remember what POES uses to generate its graph.) Also, it uses a single color gradient to indicate intensity, which makes it a little harder to read. However, it has this really handy “view line” to show the limit of where you have to be to see the aurora. It also clearly shows the terminator and location of the Sun, which is kinda handy too.
So check it out. It might help you figure out if it’s worth hoping in the car and driving to a dark site. And if you aren’t inside the “view line”, you can always check out the pictures on spaceweather.com
