    PPAS from last 2 nights - note site change after I went back home from RMCC
    Observatory. Satellite highlights include ETS-6 (23230, 94-56A) with 1X
    flashes and several new objects for me. Deep sky objects were phenomenal on
    Sunday night.

    Notes:
    1) My identification of 1 sharp flash as SATCOM C5, listed as out of service
    since Mar2001. This was a quick silvery white flash near the rather orange
    4th mag alpha Cancri, and about as bright. Kevin et al, might want to check
    on this sat.
    2) Timings on minimas. I don't see this object in any PPAS data - but it
    seemed variable to me.
    3) Timings are on minima - sharp decline followed by a flatter return to
    brightness. Difficult!
    4) Strange - caught first two flares as white and bright (equal to Deneb as
    it passed it) then switched to orangish color and a mag 4->5 smoother cycle.
    5) Could only get 1 cycle as it was an UNID at first- it had also been +2
    very low in S which caught my eye. Always listed as S in PPAS database - has
    it changed?
    6) ETS-6 again - many more flashes than this period, which started around
    2:30 UT! Several flashes 1X
    7) Very difficult, timings on minimas again but looks like I missed a few.
