Observed one-power TDF 1 (88-98A, 19621) flashes last night (2000 Feb 14 UTC) from 2:49:04 to 2:54:11, when its position went from about RA 5h 09m, Dec -5.00 to RA 5h 14m, Dec. -4.93 (2000). They were three full periods, then seven half-periods, then three full periods. (It is possible that there was one more one-power flash before my first one, but at that moment I was observing in binoculars.) The middle flash (4/7) of the half-period ones was at about 2:51:45.4. That's very close to Mike McCants' estimate of it flashing about 12.5 minutes later each night. At least during the last several nights, the flash period has been accelerating significantly. A few days ago Mike wrote: ] The timed period of Feb 6 was 33.00, the timed period last ] night was 32.71 seconds. This difference of 0.29 seconds is ] "not a mistake". ] ] 88- 98 A 00-02-06 01:26 MM 528.0 0.3 16 33.00 ] 88- 98 A 00-02-09 01:59:36.9 MM 457.9 0.2 14 32.71 Last night I got a flash period of 32.27 seconds (hopefully at least reasonably close to Mike's results, since he was using a telescope!): 88- 98 A 00-02-14 02:54:11.0 EC 322.7 0.1 10 32.27 mag +2.0->inv The observing location was BCRC, 30.314N, 97.866W, 270m.
