    There is now a report on sci.astro.satellites.visual-observe from
    David Oesper in Ames, Iowa of an "expanding rocket plume" at 2:40UT
    on Nov. 9.
    
    I would assume that this was the orbit circularization burn for the
    recently-launched Navstar 56.
    
    The current elset is just before the observation time:
    
    NAVSTAR 56 (USA-180)
    1 28474U 04045A   04314.06115767  .00053845 -36279-6  44335-3 0    85
    2 28474  39.1344 278.1972 6072761 196.6007 128.3232  4.04156181   130
    
    Here is my guess for a circular orbit:
    
    1 28474U 04045A   04314.10000000  .00000000  00000-0  00000-0 0    00
    2 28474  55.0000 282.0000 0001000  16.0000   0.0000  2.00000000    00
    
    Here is a prediction with this elset for Huntsville, AL:
    
       Lat 34.7 north Long 86.6 west

    GPS circularization burns have been seen even lower in the sky than this.
    
    It should have been even higher in the sky for observers farther west.
    
    When there is an updated elset for 28474, it will be obvious
    whether or not this explanation is correct.
