    update to previous, sure enough,
    the first +4 flash out of shadow & into
    sunlight immersion was ~ 0834:37.8 ut
    there may have been a +7 (penumbra?)
    flash ~ 0834:16 marginally seen & not split.
    hummm it occurred to me after the fact,
    naturally, that I should have reset the
    clocks during shadow to see if >immersion
    the shadow had effected the timing.  I 
    suppose I could still do that, but I'm a 
    little sleepy.  the pre_shadow PPAS ...

    the flash period had stabilized at 20.838s with a 0.001s resolution 
    with the earlier PPAS report 4 hours ago

    the 0726 ut is merely to show the 5h15m duration.
    intermediate weigh_points do show the linear spin up at
    ten-thousandth of a second level, but who's counting (other
    than Rob :)  and the variation since 03sep shows a spin up
    (flash period decrease) of ~ 0.011 sec/day.
    what is the limitation, if any, to a constant spin up for
    a near_geo with perigee at 35,720 km.  in 5.5 years will it be
    a 'constant' +4 blurr ?  could it spin so fast you could not
    see any glint, or fly apart from centrifugal force,
    or will it settle into a range of increases and decreases
    in spin rate as has been reported for other sats.
