    Due to horizon trees, I often am 'forced' to point
    near eclipse, and sometimes the bino 5* fov or scope
    3* fov does not leave enough room for 'error.'  I saw
    a post from David indicated that he did see a 2d pass 72A ok
    although I did not compare the UT times to see how it
    matched relative to your non_obs.  but looking now :) David
    saw it "again" 12sep 2055 ut, ditto PN, hummm, interim
    of ~ 7 hours, but only 1 rev, 97 min, from Ted's 0144.
    I suppose it could move lots in 97 mins if it fired...
    re eclipse predictions in general and specifically,
    I was watching milstar 3 last night and it faded in E and
    I noted the time without knowing in advance the predicted
    eclipse, and I then ran the text_ephem w/eclipse in Guide8
    and the prediction agreed with the obs within a second or
    2 (time)!!  (Guide was open and the data was a click or 2 away)
    I have several apps that predicted shadow, and some variation
    is noted in the predictions, I think I have seen up to 10 secs.
    easier to trak sat into shadow than to always see it coming
    out.  meanwhile 72A still seems too low for me :(
