Hello all, Just went out to observe Superbird A (#20040) in exceedingly clear skies. If it weren't for the nearly full moon only 11 degrees away, the flashes would have been visible with the unaided eye. I observed flashes with 8 x 56 binocs from 2:45 UT to 2:53 UT, 11 March 1998. Peak flashes were right at the predicted time (around 2:48:30 UT). 1 minute either side of the peak, flashes were also visible on the half- period. Phase transition took place about the time of the peak, with the previously dimmer odd half-flashes overtaking the brighter even = half-flashes. The even half-flashes subsequently dimmed so that only the odds were visible. This is the typical behavior that we've noticed in past years. I did not have a stop-watch handy, so was not able to time flashes. However, I do have a good estimate of the peak brightness -- about 3rd magnitude. Flashes were about twice as bright as the nearby 3.90-mag star HD#083618, which was in the same field-of-view. Of course, flash magnitudes are quite subjective, and estimates will vary from individual to individual. I've noticed that my estimates always = seem to be brighter than "the mean," so perhaps my eyes/brain have a fast integration time! ;-) --Rob
