    I have received a few private communications regarding my PPAS reports on
    flaring geosats. They have brought up several good points:
    1. My reports do not lend themselves well to the derivation of phase angle /
    etc because they are not positional nor at shadow entry.
    2. They do not quantitatively aid in predicting where to find flares
    opposite the shadow edge or "purple dot" position.
    3. They don't represent the visual appearance (they aren't really steady,
    overall) and I would add that my annotation of FGS (flaring geosats) will be
    lost in the PPAS reports.
    My responses:
    1. This is true, and can't be rectified. However, all of the objects have
    Space-Track or classfd.tle tle's.
    2. The reports were intended to be qualitative, hopefully a catalyst for
    future observers. My first experience with these objects was astonishing and
    I was unprepared for the number, ease, and beauty of these objects. I am
    posting reports so that others (and future readers) will be ready to see
    what I have seen, using other resources of course, in parallel.
    3. I hope that either a PPAS observing code is added or a definitive
    judgment can be made to use a more appropriate code than "S" with the
    soon-to-be forgotten FGS note. Any thoughts?
    I still have a bunch to report - naked eye comets, space shuttles, and the
    natural gas industry continue to delay them, but afford the opportunity to
    report in a more informative way, if one can be settled on.
