NOTES:
-------
(1) The observations of the 24th August produced an orbit with a good
    inclination but a small spread in mean motion. However I then had a
    spell of cloudy weather ( whats new?) so was unable to get follow
    up observations.

(2) However with the invaluable assistance of Mike McCants a search was
    carried out using a spread of the possible mean motions. As a result
    it was acquired in 7 images on the 29th August and in two images on
    the 31st August so now the satellite has a good orbit but the
    disadvantage in that it is a faint satellite at about magnitude +14
    so now doubt will soon be lost once it goes out my range. The orbit,
    computed by Mike,is attached - does not include the observations of
    the 29th August as those images were only measured after Mike had
    computed an orbit from the 24th and 31st August 2014 observations.
