Observed a number of satellites last night, including 4 of the objects
associated with the recent Iridium launch.  The four objects were spaced over
at least 10 degrees along-track on a 22-degree culmination pass in the west. 
Acquisition of the first object was above Sirius at about 3:45:40 UTC (May 7th
UTC), magnitude 7.  Scanning forward and backward along track, I located three
others (and possibly a fourth, briefly), also in the magnitude 7 range. 
Binoculars used were 8 x 56.

Others satellites observed were:

#20443 (Spot 2 R/B), magnitude 4
#20967 (Cosmos 2106 R/B), mag 3.5
#12054 (Cosmos 1220), at a surprising magnitude 2 passing very
             close to Arcturus
#23342 (Resurs 1-3), mag 4
#23405 (Cosmos 2297 R/B), mag 3.5 (extremely close conjunction
             with Alpha UMa)
