Not sure if this should be posted here or on the solar system forum. Perhaps we need a "Dark sky" forum! :-)
Last night I had a class out moon observing (yes it was actually clear for once!) and aroud 10.50pm CDT an aurora became active. We watched it for around 30 minutes while it fluctuated in intensity. At times just a glowing arc was visible about 10* up from the northern horizon, and at other times fast moving rays were visible reaching at times to around 40*. The aurora was a strong green colour. The arc was still visible when we packed in around 12.30am.
Our location was in Minnesota at about 44* lat.
Cheers,
Maurice
