    NOTES:
    -----------
    (1) Recent unknowns. There has been quite a few unknowns recently
        but thanks to the efforts of Ted and Mike most have been
        identified. It would seem that in recent times SPACETRACK
        is having a problem tracking certain objects so elements have
        usually not been available. This applies particularly to the
        12061 launch where two of the objects = LUCH 5B 12061A and
        YAMAL-300K 12061B were missing for several weeks and featured
        as unknowns in my reports.
    
        Of the two unknowns reported yesterday Mike identified one
        as DIRECT TV 1-r #25937 that had changed its rate of drift and
        Ted managed to identify the Unknown seen on Nov 19 as the same
        one seen yesterday which turned out to be UFO-F02 last observed
        some 200 odd days ago and which had apparently performed an
        orbit change since last positively identified so is apparently
        still operational.
    
        In recent weeks there has been quite a spate of classified
        geostationary satellites moving about so there are currently
        about half a dozen or so that need checking every observing
        session. These include PAN, USA 237, MERCURY 1 ,MERCURY 2,and
        USA 186 ( currently lost) because unobservable due to earths
        shadow but will soon be clear after which it will soon be
        recovered.
    
        VORTEX 6, if still operational, should do an orbit change any
        time now. Once the orbital period reaches about 1.0032 revs/day
        it does a boost to a new orbital period of around 1.0021 revs/day.
        The orbital period is now about 1.0033 revs/day so its change is
        a little overdue.
    
    
    
    Cheers
    Greg
