NOTES:
--------
(1) Purpose of session was to try and capture USA 129 and USA 186
    in the same field of view as they were predicted to pass over
    at about the same time and seperated by only a few degrees.
    However almost total cloud prevented this being possible.

(2) Despite the cloud it was possible to image the satellites, but
    not together, nor in the same area of the sky so I think I
    have the identities correct with USA 186 running about 2m 18sec
    late and USA 129 running about 38 seconds late - idents are
    subject to correction by Mike and/or Ted.

(3) Two other classified satellites imaged through cloud.

(4) I want to get one more good session on the visible KH satellites
    before I change the optical system to the 8 inch f/3.67 for the
    next few months.

Cheers
Greg
