NOTES:
-----------
(1) Near perfect night. Looking for unknowns and lost satellites.

(2) Unknown 1 - fairly variable - dont really believe the APEX
    magnitudes -possibly too bright at end but satellite low in east and bright
    sky so maybe it was brighter than it looked. Moving northwards.

(3) Unknown 2 - somewhat more difficult. Quite variable - in some images
    invisible - lost it when it became too faint low in the north as it
    moved northwards.

(4) Still have several fields to examine but first impression is that
    nothing unusual.

Cheers
Greg
