    Hi
    These observations were made using my CoSaTrak system whilst doing
    positional observations. The satellite/s were normally observed for at
    least two minutes of the transit. The field of view of the CCD camera
    was approximately 3.3 degrees as seen on the video monitor.

    invisible
    
    Cosmos 2172 ( #21789 - 91079A ) is a geostationary satellite seen by accident
    when it did a ~3 second flash to +4 approximately. Unfortunately I was busy
    tracking another satellite so did not wait to see if it did another flash.
    Might be worth watching.
    
    Cheers
