With regard to: http://www.satobs.org/seesat/Jan-2012/0092.html I compared the measured flash positions (in RA/Dec) on the CCD image against a tle for 78-058B. Taking into account the delta T between predicted and measured end of the trail, I adjusted times untill predictions matched these positions (or otherwise said: untill each flash had a similar delta T as the trail end, compared to predictions). Doing so, the main flashes are on average 2.98s apart, based on five measured flash positions corresponding to: flash, UTC (Jan 9, 2012), brightness ------------------------------------ flash 1, 03:04:06.49, mag +15.5 flash 2, 03:04:09.47, mag +16.0 flash 3, 03:04:12.38, mag +16.0 flash 4, 03:04:15.28, mag +15.6 flash 5, 03:04:18.40, mag +15.3 ------------------------------------ Each of these main flashes has a secondary flash on either side, in this pattern: .*. .*. .*. .*. .*. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@wanadoo.nl Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspot.com Twitter: @Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
