    NOTES:
    ----------
    (1) Purpose of observing session was to observe OTV3 and the North
        Korean objects.
    
    (2) It would appear that SPACETRACK has the KOREAN identities correct.
        The main satellite KMS 3-2 appears to be doing a regular tumble with
        a primary and secondary brightening. One bright flash to about
        mag +3 seen otherwise primary max about mag +6.5 and second maximum
        around mag +7 - +8  on high elevation western pass.
    
        The rocket appears more or less steady with small magnitude variations,
        around mag +7.5 at 10 degrees elevation in the east.
    
        Debri #39028 was sighted in four successive images when it briefly
        appeared at about mag +10 shortly after culmination high in the west.
    
        Debri #39029 was not seen at all.
    
        I will be able to observe these objects under more favourable phase
        angles over the next few days so hopefully will also see #39029.
    
        The SPACETRACK elements are accurate.
    
    (3) Now to measure the other 20 odd satellites observed :-((((( urghhhh
    
    Cheers
    Greg
