Aurora Tonight!

The effects of solar event on the 30th of Nov should reach Earth around 19hr UT on 2nd of Dec. That means the US should see the effects of it on the local night of the 2nd of Dec.
This was not a large event, but we were caught off guard on 26 Oct when no recorded event produced a number of good auroral displays.
We would expect at least an index of 4 or larger during the 24 hrs following the arrival of this event.
