    Notes:
     1) 07- 10B : timings 50.44 (35.99 7.94) 42.89
     2) 97- 82B : difficult to determine a flash period;
       timings are:
       f 14.82 a 2.77 f 15.23 f 6.63 af 12.52 f 6.19 a 12.93
       f  5.40 f 1.76 f  7.91 f 9.33 f   1.66 f 7.92
       in which:
       a means more or less round maximum
       f means flash
       af means a round maximum immediately followed by a flash.
     3) 98- 26 A: difficult to determine a flash period;
       timings are:
       8.10 25.92 21.75 12.46
     4) 96- 29 D: timings are: 31.92 17.26 73.77
     5) 88- 56 A: timings are: (9.54 8.91 1.16) (5.85 13.68)
     6) 07- 29 B: lost my timings by pressing wrong stopwatch button.
       reconstruction from voice recording (with stopwatch beeps)
     7) 05-  4 B: A'ffA'_A' evolving to A'fA'_A'; suggesting that
       one rotation lasts 12.4 seconds.
     8) 94- 78 B: at last after several attempts to detemine a period
       in the variability. Previous attempts failed as the object's
       stellar magnitude varied too fast and the amplitude was small.
     9) 97- 82 B: difficult to determine a flash period;
       timings are:
       f 22.34 f 11.86 a 7.16 f 12.03
    10) 98- 26 A: timings f 31.22 f 20.13 f, too few to determine period.
    11) 97- 82 B: difficult to determine a flash period;
       In following the timings are on flashes except when "a" is specified,
       the it concerns a more or less round maximum:
       4.12 15.00 0.95 2.85 11.76 3.61 3.53 3.00 2.86 a 2.38 a 3.34 5.58 a
       13.63 4.08 1.10 5.37 a 4.49 4.60 a 3.71 1.23 9.46 a 4.93 3.58 1.20
       9.72 4.42 4.93 a 14.22
    12) 83- 70 A: I saw this satellite unintentionally due to its bright
       flashes. I was able to identify it as an Oko (Kosmos 1481)
    13) 07- 29 B: the more than expected period increase lets me presume
       that I miscounted the flashes.
