    Hi everyone,
    
    two sets of geostationary satellites will experience a solar eclipse on 
    1-NOV-05. 
     At 13:37 UTC there is an annular eclipse at 110.6 W. Some geostationary 
    satellites close to that position will experience a deep partial eclipse with 
    a drop in brightness by about 3 mag. This can be observed from the American 
    West Coast (although twilight might get in your way) and Hawaii. 
     Around 21:50 UTC the Moon's shadow crosses the geostationary belt again this 
    time at 51.3 E. Now the zone of annularity is broader so some satellites 
    actually will experience an annular eclipse. But due to the larger distance 
    to the Moon (as compared to the first set) the drop in brigthness is just 1.6 
    mag this time. This can be observed from Europe, Africa and large parts of 
    Asia. 
    In either case the final 5 to 7 minutes before maximum eclipse (or annularity) 
    will see a drop of 1 mag.
    
    Here are the details of 6 satellites for each of the two sets. All times are 
    in UTC.
