Superbird A continues to become less and less consistent compared to a few years ago. The classic ramp up in brightness with a dozen or so equally bright flashes during the phase shift is not apparent now. I first saw a flash in binoculars about 02:59 UT on 7 Apr. After starting the stopwatch and tape recorder I observed for about 6 minutes. The latter portion exhibited the standard bright-faint pattern. But deciding when the phase-shift occurred is difficult because the initial portion was not as predicted or I missed a few. Using my previous methods, I would get a POSSIBLE phase shift time of about 03:01:35 UT. Probably the brightest flash was at 03:01:58 UT. So I guess I am within a cycle or so regardless. I just miss the original pattern.
