AURORA ALERT: A coronal mass ejection (CME)
swept past Earth earlier today (1000 UT, July 22nd) and,
although it did not spark auroras right away, solar wind
conditions in the wake of the CME are increasingly
favorable for a geomagnetic storm. Sky watchers in, e.g.,
Canada and northern-tier US states like Wisconsin,
Minnesota, Michigan and Washington should be alert for
auroras tonight.

WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2004 Jul 23 0030 UTC

At the Nebraska Star Party last week, Auroral displays were visible on July
17th (UT) and on July 23rd (UT). I only got to see the one on the 23rd, but
it was nice, with faint bluish-green rays dancing along the high dunes north
of the lake. Clear skies to you.
