    CAUTION:  Failure to use adequate and proper eye protection when viewing
    the sun can cause permanent eye damage.
    
    One hour ago at 14:53:46 PM local MST (21:53:46 UT) on 10 Feb 2002
    I observed the ISS transiting the sun.  I used an 8 inch Celestron with
    front mounted solar filter.
    
    The prediction was made using Rob Matson's Skymap to find a reasonable
    close transit, then modifying the observation lat/long until the transit became
    a near central event.
    
    In this case, I decided to use the latitude of a road that goes far enough east
    then kept adjusting the longitude.  The total distance travelled was 45 miles.
    
    I was set up 10 minutes before the event and my watch alarm was set to go
    at 14:53 local.  Just after the beeping quit, I saw the ISS clearly.  It 
    appeared
    to have the long axis parallel with the velocity vector with the solar arrays
    at the front.
    
    I wanted to videotape it but using the P23C I could only observe perhaps 1/8th
    of the sun...not enough.  If anyone know of a way to get the full sun (perhaps
    a focal reducer) with the P23C, please advise.  I have a few more events in the
    next week.
    
    Excellent prediction from Skymap.  Although it appeared to be slightly east of
    predicted, it was within a second.
