    Notes:
    ------
    (1) Two good nights one after the other - almnost unbelievable for my
        location. Transparency excellant. Seeing ranged from 12 to 17 arc
        seconds depending where in the sky. I suspect the optics of my cheap
        4 inch Chinese refractor improve as the temperature drops.
    
    (2) Object 05024 - INTELSAT 3-F7 ( lost by SPACETRACK) is normally a
        very difficult target, seldom visible yet tonight was bright and
        steady - funny what phase angle does!
    
    (3) MENTOR 2 #25336 appeared to be quite a bit west of predicted
        position. As best I can recall it has not moved in about 5-6 years
        that it has been tracked. USA 202 is very close to it - is MENTOR 2
        possibly being moved westward and being replaced by USA 202 ?
    
    (4) Unknown was on edge of field of two images - should have followed
        it as I could see at the time that HEAVENSAT had nothing at the
        observed position.
    
    (5) If the clear weather holds till tomorrow night I will probably
        track again and try and get the few remaining objects that have not
        been observed recently.
    
    (6) Have not seen SDS-2F4 in several attempts recently, watching -4
        to about +5 minutes -- probably also done a move.
    
    (7) All processing done automatically by APEX.
    
    Cheers
    Greg
