    Easily seen despite light blue sky with Sun at -9
    
    I was alternating with 7*50 binoculars and without, around Polaris and 
    below Arcturus. At 01:10:50 a "Meteor" 84072A almost fooled me, when 
    followed at 01:11:42 by a Cosmos 75016H on the "same" track and "same" 
    brightness, but that dimmed to invisibility. 
    
    At 01:12:58 a bright (mag +1.5) pair, about .3 deg apart in pos angle 
    135 (from N=up) appeared below the star below eta Boo, only .6 sec 
    before Ted's elset!
    
    I got four points, but star ID of #2 and #4 are not 100% certain, and 
    the accuracy is low. #3 was in a group of four to five "stars", but 
    three of them turned out to be a NOSS trio (NOSS 2-3)
    
    The strange thing is that the timing is progressively early on 
    prediction, -0.6 -5.4 -10.4 -14.3 ! Had they been boosted into an 
    excentric orbit?
    
    The two objects retained their relative positions, foreshortened 
    slightly by distance, and slightly increasing the position angle.
