    Last night (some hours ago) I watched Superbird A (20040) 
    from outside my apartment, looking over the building's 
    roof.  For others who might want to see it, I believe 
    that on a given night the flash episode moves from west to 
    east (i.e., earlier in the west, later in the east).  So 
    for example, my last observed flash below was at 3:22:03, 
    and Don Gardner's -- for what I believe was the 
    corresponding bright event -- was at 3:35:14.  (I think 
    he was using a telescope, but I was using handheld 10x50 
    binoculars, making my last-observed flash correspondingly 
    earlier than his due to him seeing fainter magnitudes, 
    I'm pretty sure.)  I wish I could determine the phase 
    shift time, but it's just a bit too tricky given my 
    rustic observing method.
    I have a bit of a problem in doing PPAS reports on it, 
    because of its phase shift.  Its actual flash period now 
    is 22.6 seconds, but because of the phase shift and not 
    being able to report half-period counts, if I report the 
    actual 22.6 period, I cannot include some cycles.  So, 
    which of the following is the correct PPAS report?
    89- 41 A 02-11-14 03:22:03.0 EC  418.1 0.2  37 11.30  +3.5->inv
    89- 41 A 02-11-14 03:22:03.0 EC  339.0 0.2  15 22.60  +3.5->inv
    2002-11-14 observing site:  30.309N, 97.728W, 150m.
