This evening, we finally had an auroral display. vakkotaur first commented, as we got back home from dinner, that there was a haze in the sky, but it might be an aurora. A little bit later, his dad let him know that there was an impressive display in the sky in Merrill, Wisconsin, and we might want to go look. Paul promptly dragged me out of town a ways.
There was a strong, wispy glow mostly covering the sky from the northern horizon to about 10 degrees south of the zenith, with smudges of glow all the way to about 30 degrees past zenith. It changed slowly, but noticeably once we watched for a while. It was pretty dense down toward the horizon, too. I couldn't see any color in it; Paul said he saw mostly deep red. He said it was an impressive display. I'll take his word for it.
Still, it didn't look like the shimmering curtain that's the usual description of aurora. I guess I'll have to catch another display the next time one is visible as far south as Fairmont.
