    (1) Both 90026 and 90027 do a "flare" of about 3-4 magnitudes when at
        phase angle 48-49 degrees. 90027 is the most dramatic, flaring to
        about 2nd magnitude for about 30 seconds.90026 is about 2 to 2.5
        magnitudes fainter.
    
    (2) Track of 96072A on 9 Dec rather erratic as I had to do it manually
        so there may be some small scatter between the various points.
        Last point (20h23m09.4s UT) was just before shadow entry so
        satellite already fading.
    
    (3) Next tracking session monday or tuesday - weather permitting.
    
    Cheers
    Greg
