    Hi everyone in the Pacific region,
    There will be a partial eclipse of the Sun as viewed from geostationary 
    satellites near longitude 172.5 East on 4-SEP-05 between 5:30 UTC and 7:30 
    UTC. The following three satellites should show a drop of in brightness of 2 
    mag of which 1mag will be within the 10 minutes before and after maximum 
    SPACENET 4  (1991-028A)  at 172.0 E  maximum at 6:43 UTC.
    INTELSAT 605 (1991-055A) at 174.1 E  maximum at 6:42 UTC.
    INSAT 2B (1993-048B)  at 172.1 E  maximum at 6:45 UTC.
    For observers along the American West Coast these satellites will have an 
    elevation of about 10 degrees which might be a little too low (I don't know). 
    For observers in New Zealand they would be high in the sky but at that time 
    the sky is still rather bright (between civil and nautical twilight).  By far 
    the best conditions for observation would be Hawaii with a high sat elevation 
    and dark skies.
