At last I managed to see ETS-6 #23230 94-56A from Sweden. I was watching from UT 16:56, 30 seconds naked eye, then 30 sec in 7*50 binoculars etc. After two minutes I found it in binoculars, and shortly after the flashes were mag 1-2. Then, I phoned my friend who had helped me trying to find this one on previous opportunities, and unfortunately I missed the transition event during that time. Here are my flash timings; add 16h 00m 49s for UT: 58:46.61, 58:49.59, 58:57.87, 59:00.74, 59:09.30, 59:12.03, 59:20.62, 59:23.39, 62:12.49, 62:18.11, 62:20.96, 62:23.64, 62:26.46, 62:29.47, 62:34.96, 62:40.95, 62:46.26, 62:51.90, 62:57.51, 63:08.78, 63:14.64, 63:20.13, 63:25.82, 63:31.59, 63:42.68, 64:05.18, 64:10.75, 64:16.43, 64:27.78, 64:33.88, 64:45.21, 64:50.48, 64:55.96, 65:01.52, 65:12.80, 65:24.07, 69:26.41, 69:49.04, 69:54.73, 70:00.22, 70:06.36, 70:11.27, 70:22.67 (Further gaps are intentional, because I only had about 60 memory places left on my stopwatch.) As numbers, these show very little, but visually the first few were a bright flash followed 2.9 seconds later by a secondary. During the break, the secondary became the brightest, and a new tertiary series appeared 5.7 seconds after the secondary. In the beginning of this second phase I did see one faint corresponding to the primaries, and one faint between the secondary and tertiary. In the final phase, the tertiary flashes were the brightest.

That is, for example, the time from the ... This, and the horrible number sequence above, is hardly a problem using a plot of the absolute time of each flash, minus an integer multiple of an assumed period (program SYNODIC). These ETS-6 timings are shown in http://www.algonet.se/~b_gimle/gif/ETS-6.gif When the period is correctly choosen, all flash series appear as horisontal bands. Missing timings are just missing marks, and do not affect subsequent timings, or require additional arithmetic or guessing the number of periods missed. -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2615 N, 18.6206 E, 33 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www2.satellite.eu.org/satintro.html -- ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
