    NOTES:
    --------
    
    (1) #12046  FLEETSATCOM 4 - long slow variable, mostly fairly bright
    (2) #23967  UFO-F07   - rather faint but due to phase angel-low in west
    (3) 96044   First time amateur observtions so can be removed from
                Int96.tle . Quite an easy object.
    (4) 96047   Bit of a swine to observe - long irregular period and
                most of time invisible
    (5) 96127   Same story as 96047
    (6) Not seen  -- 96086, 96089 ,96143  - either too faint/too long
        invisible or not there. Next time I track I may use the 6 inch if
        Im not too lazy to change my setup....
    (7) The unknown seen two nights ago could not be located so would
        appear to be a "drfiter" rather than being in a near stationary
        orbit.Wish these satellites would carry ID books or some means
        of identification - I have to!!
    (8) Seeing 13-15 arc seconds - seems this is my "good seeing" which
        shows what a **** location I have!!!
    
    Cheers
    Greg
