    Hello All,
    
    On 2000 April 5 at approximately 05:25 UTC (April 4, 23:25 local) +/- 5 
    minutes, I observed a  relatively bright satellite (comparable to Capella, 
    perhaps +0.5 Vmag) just east of Auriga, or about 330 deg. azimuth, 40 deg. 
    elevation, and travelling north.  It exhibited no fluctuations in 
    magnitude.  The end of the visible track occurred at 340 deg. azimuth, 15 
    deg. elevation.  (Allow +/- 5 degrees on positions.)
    
    It was surprising to see at that time of night so bright a satellite at 
    such an elevation.  It may have been visible for quite some time before I 
    observed it; however, I had only been looking skyward for a few seconds 
    prior.  Also, its apparent motion was almost imperceptible at first.  In 
    fact, when I first noticed it, I attributed what I thought was its movement 
    to an optical illusion.
    
    I haven't yet schooled myself in orbital mechanics, but I'm fairly certain 
    that it was not a LEO sat, given its visibility at that hour and 
    elevation.  I'm guessing it is in an elliptical orbit and was at or near 
    its perigee (due to brightness), yet at such an altitude that it remained 
    sunlit.  Although, the relatively slow movement would seem to contradict a 
    perigee orientation.
    
    Thanks to anyone who can identify this satellite and confirm or refute my 
    supposition of orbital geometry.

    P.S.  I apologize for the less-than-precise time and position 
    measurements.  I had just stepped outside to feed my cat before retiring to 
    bed, and thus my NIST-synchronized watch was elsewhere gauging the flow of time.
