    On Apr.20 I searched for USA 116 in the interval -16/+16 from the
    last elset below (at 22:30-23:03).
    Because of the wide area covered during the interval,
    and my problem of memorizing several prediction points, I looked
    mainly without binoculars, and could of course could have missed it.
    I saw only one satellite, but with lower inclination, ID'd as #10777
    
    On Apr.22 I searched the interval -75/+3 (22:04-23:22) (which still leaves a
    gap +16/+22)
    The only object with a small cross-track dislocation, and matching predicted
    track DIR and speed, was observed
    22:13:41 near RA 19:06, dec.+34
    22:14:06 near    20:09      +44
    22:15:29 near    00:23      +51
    
    This matches closely this elset, where only Epoch is changed from my search
    elset at the end of this mail:
