Looks like a good clear day, so I hope it's a clear evening for Southern California. There's a TERRIERS launch to look forwards to at 22:05 local time, see Bjoern's & my separate messages. Also: * Mir should pass over in the NW, peak elevation ~40 deg at 20:52. * Most people in the LA basin should see Iridium 30 flare at 20:52:55, just W of N but only 17 deg high. * UARS should culminate at 77 degrees in the NW about 21:41. I'd urge you to run your favorite prediction s/w for more exact timing & positions. Best, Mark
