    Notes:
    --------
    
    (1) Observing conditions very poor at start- cirrus and full moon,
        improved later but eventually stopped because of mechanical problems-
        faulty connection in elevation drive.
    
    (2) #28500 (Del4 Demo) seen for a few seconds when it brightened from
        invisibility to about mag +7. Could not find it on integrated
        images so must have a faint minima.
    
    (3) #90065 - piece of mylar - been behaving itself for several weeks now-
        almost spot on prediction.
    
    (4) #90016 - not seen - usually an easy object but not seen on two
        attempts during the observing session - is it busy moving again?
    
    (5) Now back to one of my favourite occupations - recovering files/data
        from a crashed hard drive! - suspect computer got too hot ( we have
        had a "heat wave" the past few days ) and FAT (File allocation
        table) destroyed ( or something!).
    
    Cheers
    Greg
