    Observations of satellites with (more or less) periodic brightness
    variations.
    The reported times are those of the last timed maximum.
    7 x 50 binoculars used. Sky was moderate:
    moonlight in the evening, haze in the morning.
    inv: invisible in  my 7 x 50 binoculars (mag +8.5?)

    Notes:
    1) 78- 96 A: nice object with flashes and secondary flashes.
      unexpectedly regular for such an object.
    2) 97- 52 C: timings reconstructed from voice recording due to
      not resetting stopwatch prior to observation.
    3) 02- 54 C: followed by naked eye near culmination point.
    4) 05-  4 B: followed by naked eye near culmination point.
    5) 07- 29 B: neo = naked eye object in maxima; nice flasher;
      counted in 11 groups of 10 maxima.
