    It appears that Gerry Smerchanski has discovered a new GEO flasher.  Below
    are the circumstances.  I also observed the possible last half of the 
    flashing period around 03:37-03:40 UT on 18 April 2000 from Falcon, CO.
    
    I was unable to ID the satellite (program input error).  Mike McCants ID'ed
    it as TVSat 1:
    
    TVSat 1
    1 18570U 87095A   00107.90581788  .00000031  00000-0  10000-3 0  7888 
    2 18570   8.3377  44.7161 0065198 243.0888 116.2131  0.98915976 34316 
    
    I found no entries for it in the PPAS database.  I will attempt tonight to get
    an accurate period and flash interval.  This might be another Superbird-A
    challenge for Rob or Bjoern.  At this point, I cannot offer much guidance
    on flashing time for other locations or as days go by.  Perhaps someone can
    give a general idea if it will occur later/sooner as a function of longitude
    and delta days.
