Recently when I've had chances to time SPOT 3 (93-61A, 22823), I've always come up with a fractional cycle in the middle of my timings. For example, last night while Mike was observing the eccentric flashing UNID and it was too faint for binoculars, I looked for SPOT 3 and saw it do a few one-power flashes, at least one them as bright as +1. Here are the timings: 0 0 3:37:04.74 UTC 1 20.91 2 2.09 3 13.91 4 5.44 5 1.84 6 13.84 7 21.06 3:38:23.83 From longer observations on other nights, I'm fairly sure that the fundamental flash period is about 21 seconds, but I can't quite figure out how to analyze the above timings, specifically numbers 2 through 6, which are similar to "non-fitting" timings on other evenings. It seems that either 2 and 3 or 5 and 6 must constitute a fraction of about 3/4 of the fundamental period. If so, would that be a "phase shift"?
