I saw flashes from Iridium 18 aka 20, NORAD#24871, on two passes last evening: Several flashes at regular time intervals of about 1 second, but irregular brightness pattern, were seen from 1998-Jun-14 04:01:05 to 04:01:10 to the east around AZ 75, EL 35. The brightest flashes were about mag. -1. Later the same evening several flashes in a similar pattern from the same satellite were seen from 05:42:15 to 05:42:23 +- 2 seconds low in the west around AZ 270, EL 20, the brightest about mag. 0. After the flashes were seen on the first pass above, I turned my eyes to the west to see a nice overhead pass of MIR. -- Frank Reed Scottsdale, Arizona, USA 111.898W 33.484 N 1227 feet
