Cloudy in northern Minnesota this early morning, but if you’re reading this from the northern U.S. or southern Canada, be alert that a minor aurora storm is in progress as of 12:30 a.m. July 15. Auroras are potentially visible across Maine, upper New York State, northern Michigan, N. Wis., N. Minn., N.D., Montana and N. Washington resulting from a blast of particles from the sun combined with a southward tip in the sun’s magnetic field┬áin the Earth’s vicinity.

    • Daniel,
      Glad to hear Germany got some aurora. I have wondered too. Sometimes they are very useful and accurate. Other times it looks like n. Minnesota is covered in aurora and I see only a very low arc. Another time the oval was positioned far to the north in central Canada, the Kp was 2 (green) and yet we had northern lights here in Duluth. I even called the space weather people to talk about that one and they couldn’t say why. Like much of the aurora-predicting business, best to take with a grain of salt.
