NOTES:
-------
(1) To the naked eye looked a normal night sky - ie pretty poor but
    found I had to use longer than normal integrations. Eventually
    became so poor I checked the telescope objective and it was somewhat
    misted over so increased the current through the heating resistors
    that warmed the lens. However made no real difference. Humidity very
    high 85% - and eventually the mist came down and put an end to my
    suffering.

(2) Apex refused to process about three quarters of the images with the
    comment - "insuffcient stars" - APEX requires a certain minimum
    number of stars to perform a plate solution and uses the Tycho star
    catalog which goes down to about magnitude +12 so obviously the poor
    transparency due to the high moisture content killed the fainter
    stars so the majority of images had to be measured manually.

(3) Several of the objects had not been observed for a long period due
    to faintness and long and irregular variability - especially the
    rockets and the DSP satellites so sometimes an image would produce
    a short trail and in the next image a single point from a flash
    and sometimes several flashes in a row so there will be some scatter
    in the positions as not always possible to determine where the
    centre of the "trail" was. Objects recovered were  DSP F10r ( last
    seen about a year ago),Magnum 1 rocket  (last seen more than a year
    ago ), and DSP 13r ( last seen almost a year ago).

(4) Mercury 1 appears to be geostationary and not drifting at the moment.

Cheers
Greg
