NOTES:
--------
(1)  After a week of heavy cirrus cleared for a few hours so managed to
      observe a few satellites dodging clouds. Measuring almost complete
      but got myself messed up and wasted a lot of time and now mentally
      exhausted. I seem to have found two unknowns which do not appear in
      my current database.

(2)  The first one caused the problem as I was waiting for STPsat #37229.
      I initially mistook UNKNOWN 1 for STPsat but soon found that there
      was something wrong as the time residuals were not constant so
      obviously a satellite with an almost similar track angle but a
      different orbital period. Eventually sorted things out as I also
      had observed STPsat in several images and it was running close to
      the predicted time ( within in a second or so ), so eventually
      identified what belonged where. I can find no match for this unknown
      so either I missed something, or its not in my database which was
      updated on the 15th January. A bright unknown at magnitude +06 is
      rather unusual.

(3)  The second one also has no match to anything. Many thanks Kevin for
      your attempt to identify. Let see if anyone can come up with the
      same or better.


Cheers
Greg
