NOTES:
---------
(1) Main purpose of session was to track 90108 - got a good observation.

(2) Unknown seen - about magnitude +6 steady in portion observed

(3) Apart from 90108 all the other satellites observed by accident.

(4) Rather surprised by how bright CUSAT 2 was - about magnitude +2
     steady in portion of track observed.Probably attached to Falcon 9 
rocket?

Cheers
Greg
