    Now, elset 70 for day 10297 shows a pass two minutes before that by elsets 69 and 68 
    (identical, day 10290)
    The biggest problem is that these,and no.67,  have zero Bstar, and negative ndot2, which 
    does NOT agree with the increase in mean motion!
    
    With six synthetic observations on the passes after the epoch of 67,69,70, and one for 
    Mike/Ed,
    I get these elsets with an RMS of about 3.5 degrees (with MM adjusted!) and 14 degrees 
    resp.
    CZ-3A R/B not likely!
