    Very low pass (99 miles, 160 km) of Mars Odyssey Delta Rk tonight 
    -- at Austin, it's near zenith, west-to-northeast at about 2:36 
    UTC (solar elev. -12 deg.).  Ground track (subsatellite point) 
    goes north of Austin.  If it's consistent with other Deltas, its 
    Quicksat intrinsic magnitude should be around +3.5 (standard mag. 
    approx. 5.0).  Latest two elsets I could get:
    
    DELTA 2 R/B(1)
    1 26739U 01013C   01188.66484163  .05890292  67663-5  52950-3 0  2139
    2 26739  39.9697 184.6889 0180659  20.5352 340.2804 16.03982816 13292
    DELTA 2 R/B(1)
    1 26739U 01013C   01188.54027291  .06111626  67594-5  58624-3 0  2125
    2 26739  39.9688 185.5130 0185771  19.5166 341.2657 16.02495593 13277
    
    I'm not sure how large the visibility "footprint" is of an object
    this low.
    
    This one must be decaying pretty soon.
