    Hi,
    
    
    I just watched ISS made a short pass (+/- 1 minutes) over Huntsville
    few moments ago, with a mag of -0.5 per Heavens-Above, around the
    time as listed below:
    
    Event 			Time 	Altitude  Azimuth  Distance (km)
    
    Rises above horizon  	18:19:06 0 	312 (NW ) 2,229
    Reaches 10 altitude 	18:21:09 10 	312 (NW ) 1,379
    Maximum altitude 		18:23:52 66 	306 (NW ) 408
    Enters shadow 		18:23:52 66 	306 (NW ) 408
    
    This is the brightest ISS that I have seen so far. I will appreciate if
    anyone can point me to any online reference on how to take pictures
    of a passing satellite.
    
    Thanks.

    ps: Sorry Rob, the first e-mail was intended to Seesat-L,
        but I didn't check the address when I pushed the "send" button.
