NOTES:
-------
(1) Lot of cloud around but able to secure 14 images between gaps,
     measured 4 of them manually - can do more or all if required.

(2) Slightly high in elevation - last position reported is just
     before shadow entry that was predicted for 17h17m41s - satellite
     running about 2 seconds ahead of predictions at 42 degrees
     elevation where shadow entry.

(3) Used 2 second exposures on account of moving cloud and bright
     moon. Stars as faint as magnitude +10.5 recorded in images.

(4) I accidentally imaged about 8 other LEO sats - still to check
     what they are and if any classified or worth while reporting.

Cheers
Greg
