Cascade River Aurora

Northern Lights over the Cascade River where it crosses The Grade near Grand Marais, MN. Last night my friend Roger and I were out looking for the Northern Lights and were disappointed by the heavy cloud cover and rainfall that dominated the early part of the evening. Eventually, though, the clouds parted and treated us to some incredible Aurora viewing. A couple of days ago there were a couple of Coronal Mass Ejections that left the sun and were headed straight at Earth. At first spaceweather.com was saying when the CME's hit our atmosphere they did NOT trigger any geomagnetic storms. After the initial impact, however, the arrival of the CME's compressed Earth's magnetic field and lit up Auroras around both poles.
