    Object 68-14B showed up yesterday as an elset that was not
    in my file of all tles.  Object 68-14A is OGO 5.  Object 68 14B
    is its Agena rocket upper stage.  Both objects have an orbital
    period of a little over 2 1/2 days.  The last previous elset for
    68-14B was in 1970.
    
    Object 68-14B (NCat 03145) is currently making perigee passes
    over the northern hemisphere every few days at a height of
    about 22000 miles.  I would guess that its magnitude near
    perigee will be about 12th magnitude, but it could be a little
    brighter or fainter.
    
    It should be similar to the object that has been tracked by
    amateurs as NCat 03956 (69-46F).  This object has a period
    a little greater than 2 days and makes perigee passes at a
    height of only 4000 miles.  At that range it is about magnitude
    9 or 10.
    
    These objects are affected by lunar and solar gravity, so
    generating predictions is not simple for a time period more
    than a week or two.
    
    Here is a "current" elset generated by my int3 program from
    an elset determined by observations:
    
    1 03956U 69046F   06078.00000116  .00000000  00000-0  00000-0 0    00
    2 03956  25.1524 325.5258 8183497 161.2318  27.1852  0.46184855    02
