    these are pretty tight.  the RA is ~-0.02 based
    on appulse ~ 7 sec after 1st pt.  
    this was relatively high pass and
    I'm seeing that ("parallax constant") time error 
    thing again first pt (near my latitude) is :00.0 ontime,  
    thereafter pts tend to add a 1 tenth early northbound.
    that seems too consistent to just be a coincidence especially
    when I saw the same thing the other day with 88
    culm pass of 91082A.  please comment, is that a real
    observational anomaly or just a coincidence.  
    thinking "visual doppler shift" / parallax, with passes
    in east & west parallax, if any, is high / low in elev
    and on high culm overhead passes, south / north it shows
    up as time early or late?? (talking in terms of high inclin
    sat) or is this time resid all a coincidence?
    
    peered for 91082A at 0233:40 in my SW+30 but 
    too faint to see, although something flared
    in the vicinity but not long enough to get a fix.
    
    also saw a sat in 10x FOV
    ~ 0221:05 17.784 RA +23.85 Dec +6 vM southbound
