NOTES:
--------
(1) Have just found this object while going through images secured on
    first pass very low in east and sky flooded with freeway lighting.
    Around azimuth 117 degrees, 12 degrees elevation. Not an easy place
    to observe

(2) It looks like it could match Teds first boost orbit at 11h30m49s UTC
    elset #71001 except the object was about 84 seconds early and about
    3.4 degrees lower in the sky. I do not find a suitable match in my
    element database.

(3) The second last position not that accurate as satellite already
    entering earths shadow and the last position is even less accurate as
    essentially now invisible so end of trail not well defined.

(4) I have not finished checking all the objects seen on the first pass,
    let alone do the second pass which was a high elevation pass
    but was observing at about 18 degrees elevation so hope I may have
    got it.Have about 500 images to examine first so its going to be
    a long day :-((.

(5) Since the object observed looks promising I will now ignore the rest
    of the first pass and check the second pass and later do everything
    as several other classified satellites seen so worth processing all
    ( manually) and will report all interesting objects in due course.

Cheers
Greg
