Keep Watch for the Northern Lights Tonight June 1-2

[Jim Almquist]

I just read this in the Duluth News Tribune:

Last night’s aurora crept up out of nowhere. Space weather forecasters predicted a very small chance of a minor auroras for mid-latitudes, but a sudden change in the direction of the interplanetary magnetic field (IMF) set Earth’s magnetic field a-jitter, sparking a nice display of northern lights. The storm’s still raging across Siberia this afternoon with no sign of letting up.

Dang, I read this too late.
