     Notes:
     ------
    (1) A poor night at the start with much high cloud about - got worse and
         eventually had to close down- now I recall why I prefer radio tracking!
    (2) USA 125 R2 -- only one position - faint at about predicted position-
         if discordant throw out...
    (3) NOSS 3-4 objects - tracking in and out of cloud so magnitudes varying-
         satellites were steady
    (4) USA 129 tracked through very heavy cirrus - satellite easy but a little
        difficulty in deciding where star trails ended so positions could be
        a little scattered.
    (5) NOSS 8(A) seen as "unknown" as I did not predict it and identified
        when measuring.
    (6) NOSS 0(A) - invisible most of pass through cirrus but brightened
        briefly for the positions obtained.
     
     Cheers
     Greg
