March 31, 2020 Auroras

Itasca County, MN

A high speed stream of solar wind, along with a big of a southward-pointing magnetic field in that solar wind stream, created conditions for auroras, including a brief substorm around 10:45 PM. This was the first substorm I had seen in quite a while.


The substorm began around 10:44.


The peak of brightness a few minutes later.


By 10:55, things were starting to dim a bit, but the structure persisted until about 11:00 or so.
