    Observations of satellites with (more or less) periodic brightness
    variations. All observations by 7 x 50 binoculars.
    The reported times are those of the last timed maximum.
    Unless they have format hh:mm then it is an approximate time.

    Notes:
    1) 1992-052A:
      Variationspattern evolved from aFA'=> FA'.
      In following list of timings:
      A = bright round maximum
      a = faint round maximum
      f = faint flash
      F = bright flash
      Flash times are followed by type of maximum
            sometimes accompanied with magnitude approximation
            between parentheses
      A 7.03 a 14.18 f 6.20 sum = 27.41
      A(+4.5)6.46 a 14.05 f 5.98 sum = 26.49
      a 7.12 f 13.39 F(+0) 5.32 sum = 25.83
      A 7.97 F(+2 reddish) 13.86 f 6.61 sum = 28.44
      a 6.25 f(+4 yellowish) 13.99 f(+6) 6.56 sum = 26.80
