    Peter Wakelin's observations of 2007 Apr 08-09 UTC have further improved the
    orbits.
    
    I have renamed 07005B from IGS-O3 to IGS-OVS, which denotes Optical Verification
    Satellite.
    
    I still have some doubt as to whether 06037A and 07005B need to be swapped
    (again!), but it will take some analysis before a decision can be made.
    
    I suspect that the mean motion of my 07005E elset of epoch 07098.03486949 may be
    a bit too high, so it could be many seconds late. The 07005E and F elsets are
    the least reliable, due to the small number of underlying observations.
    
    Standard magnitudes, where stated, are those of the corresponding 03009 objects.
