    Notes:
    ---------
    (1) Took longer than normal to measure because quite a few satellites
        tracked in "tracking mode " - ie camera tracking on the satellite.
        These have to be measured manually as I have not yet tried to use
        APEX in this mode - according to the author of the program it can
        be done
    
    (2) WGS-F2 # 34713 now on station at 60 degrees East, very close to
        DSCS 3-13. Cant be a very big satellite as its fainter than the
        DSCS satellite.
    
    (3) USA202 still sitting next to Thuraya 2 and evesdropping.
    
    (4) Track of USA125r2 (#23947) not a good one - maybe the CoSaTrak
        program driving the telescope did not like having to interpolate
        between such big jumps in dec/ra as the satellite passed close to
        the south celestial pole. CoSaTrak interpolates between predictions
        to try and do a smooth track in between predictions.
    
    (5) Del4Dem played difficult tonight with visibility spells far apart
        as it varied in brightness, and 96080 was even worse - only saw it
        once, so not reported as not 100% convinced it was real.
    
    (6) Chilly conditions - camera was 15 degrees C ( warmer than
        surroundings by a few degrees) and seeing was around 13 to 14 arc
        seconds.
    
    (7) Will spend the next day or two working on a new project related to
        classified satellites but not optical so OT in this group.
    
    Cheers
    Greg
