How do I determine how high the aurora is in the sky?

Last Updated: Sep 20, 2014 06:57PM UTC
Auroras do not necessarily fill the entire sky. The citizen science report gives the following options:
  • northern horizon only
  • 45 degrees north
  • overhead
  • 45 degrees south
  • whole sky.

If the aurora is low in the sky and you are facing north, select northern horizon only. If the aurora is halfway up in the sky, then it is at 45 degrees and you should select whether you are facing north or south. If the aurora only appears directly upward, it can be described as overhead. Lastly, an aurora can sometimes cover the whole sky!
