Shortwaves were dead

There was very poor shortwave propagation yesterday. Now I see why...

A Sunday Morning Report

[BRock97]

Hell, it would have been nice to know this in advance...

As it was, got out of work about 0800Z Sunday morning and as I was driving home, thought I saw the most bizarre clouds. When I pulled into the driveway, there were these flashes that moved from west to east in the night sky. Since I live next to a small airfield, I assumed it was the lights from there, but when I looked in that direction, they were turned off. So, drove about 20 minutes west of the big city (damn that light) and was treated to a show that words cannot describe. This being my first aurora event, I had didn't know what to expect. I sat and watched for 45 minutes as the sky literally danced. About 30 minutes in, the aurora moved to right above my head and turned into a completely different show with different bands shooting out above me.

To anyone who hasn't witnessed an aurora, take the time to travel someplace that you can view them. It is totally worth the trip.

Judging by the POES Auroral Activity graphic, things are firing up again. Damn my luck that thundershowers are moving in to cloud things up....
