3 May 1998: Laramie, Wyoming

On this night I may have missed the best part of the display because I waited until the Moon went down. The Boulder K-index was in the 5-7 range most of the night. I give times in UT minus 7.

• 2:49 - faint amorphous glow, with some clouds
• 2:52 - weak rays
• 2:54 - several weak rays up to 15 degrees, NNW-NE
• 2:56 - getting a bit brighter
• 3:01 - still glow, rays weak on non-existent
• 3:04 - rays again, one to 20 degrees
• 3:12 - satellite -4 then faded in 5 seconds, b/w Altair and Sagittarius, Iridium flare?
• 3:15 - #1 60 sec, good pencil beam bearing 350
• 3:17 - faint glow up to 25 degrees still few clouds
• 3:18 - #2 120 sec
• 3:28 - several diffuse features, #3 60 sec
