    Morning all
    As Mike has already reported I was able to get at least a 40 minute long
    track on Kevins latest low inclination find and the object is now in the so
    called CLASSIFIED.TLE collection as object 90088. For records completeness
    here are the observations made:
    Observations 02 Nov 2011
    Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa
    Kevins object:

    I can give more observations over a somewhat larger arc but lower accuracy
    if wanted as the timing accuracy was only about 1-2 seconds (obtained with 
    wide field system).
    Correction for observations reported 1st November 2011:
    The object reported as Vortex 6  #19976 was NOT Vortex 6 but ANOTHER low
    inclination object (~ 26 degrees) at high altitude. Unfortunately the arc
    observed is rather too small to give a reasonable chance of recovery but I
    am going to try.
    It is becoming increasingly obvious, and a real pain in the rear end , that
    there are MANY relatively bright objects in low inclination highly
    eccentric orbits that are not found in the SPACETRACK catalog. Less than a
    week ago I found another one - again too short an arc to get a reasonably
    good orbit and Kevin is also finding them a pest.
    So I decided that this was a new challenge for me and for the next month or
    two most of my optical tracking will be concentrated on
    (1) recovering low inclination high eccentric objects that the amateurs have
    lost due to infrequent observations
    (2) attempting to get reasonable orbits on new objects found
    Mike McCants has written some software for my homemade system which will
    make the task a lot easier and this was applied to Kevins
    object with great success - many thanks Mike for the software and the
    I have also put together two optical "tracking systems" - one for narrow
    field searching ( 1.86 x 1.37 degrees) and simultaneously a wide field
    system covering  about  7.44 x 5.52 degrees. The latter easily shows the
    brighter geostationary/high altitude objects - one field taken last night
    shows 13 high altitude satellites that I have still to identify so I have a
    lot of checking to do.
    So much work to do but its FUN!
