Hi Paul, > I saw a bright flare (about -2 magnitude) from Iridium 6 at 1039UT on 22 > Aug. 01 from the site coordinates listed below. This flare was not predicted > by H-A. This was actually a double-flare, Paul. At 10:39:00 UT, you would have had a broad dim flare (~+2 magnitude) from the left MMA. H-A may not have predicted this one if you had your minimum brightness set at +1 or brighter. However, the second (and far brighter) flare should have peaked around 50 seconds later. This definitely was a solar array flare, and it was predicted by IRIDFLAR to be magnitude -1. (Magnitude estimates on the solar array flares are far less certain due to the much looser tolerances on array pointing compared to the MMAs.) H-A wouldn't have predicted this one since it wasn't an MMA flare. By the way, you'll have another solar array flare this evening, this time from Iridium 39 at 21:29:45 CDT, 40 degrees above the southeast horizon. Predicted magnitude is around -0.5. Tomorrow morning you'll have a double-flare from Iridium 4. The regular flare will come first at 5:32:55am (mag +0.0), followed at 5:33:44 by a -2 mag solar array flare. Enjoy!
