NOTES:
---------
(1) Purpose of session was to do a complete orbit plane scan for
     OFEQ 5. 22 satellites seen of which 21 identified. The unknown
     is called 99999. The orbit plane scan lasted 101 minutes so
     got more than 1 orbit using the plane scan program kindly
    provided by Cees. Works well.

     A circular orbit determination produced the following

99-99A                          7.0

   1 16 02 25 18 04 57.1  07 55.97 -37.411 2000 5.0

     Could this in fact be the long missing OFEQ 5 #27434 ?    Not many
     brightish satellites with an inclination of 142 degrees and
     altitude about 476 kms.       Standard magnitude of +7.

(2) The object reported on 22 Feb as an OFEQ satellite is incorrectly
     labelled. It appears to be a relatively bright unknown with a
     possible 66 degrees inclination.

(3) The unknown reported yesterday has the following orbit IF
     circular. The inclination may suggest otherwise. The approximate
     range observed was about 3000 km     1
