Hi All,
Was able to time both Superbird A and Ed Cannon's GEO flasher for
longer periods last night (8 April local), and thus get some more =
accurate
flash periods. I timed Superbird for 6 minutes 46.79 seconds +/- 0.3 =
secs,
which covered 35 half-periods. This gives a half-period of 11.623 sec,
+/- .009 sec, and a full period of 23.245 +/- .018 seconds. Peak flashes
again between 2nd and 3rd magnitude.
I picked up Ed Cannon's GEO flasher at 21:05 PDT (same time as the
previous night) and was able to see flashes intermittently for about five
minutes. 89 flash periods covered 3 minutes 43.61 seconds +/- 0.2
seconds, giving a flash period of 2.512 +/- .002 seconds. I should point
out that I did not observe every single flash during this period -- some
were below my threshold of about mag 7.5. Brightest flashes were mag 6.
Cheers,
Rob
