What these numbers mean: http://www.satobs.org/position/IODformat.html ------------------------------------------------------------------------- Obtained through a very thin cirrus cloud layer. nevertheless, reference stars and trails well visible. The Centaur rocket (12-048N) appears to have stopped discernable tumbling. I could see clear brightness variation. It was +1 short after shadow exit and then generally +2 while traversing Cassiopeia. The NOSS 3-6 A & P objects were seen naked eye, steady +4, nice high elevation pass through Perseus. NOTE: I have revisited the preliminary timing calibration, noting that my delta T's came out 0.3s too early with respect to Ted's and Russel's observations and the stray Kosmos 1867 visible on one of the images. In an earlier calibration session I logged severeal Iridium satellites, and found two sets of delta T's in them 0.3s apart. I choose one of the sets as the baselines but it now appears I should have chosen the other. (indeed, over the last year or so I had noted earlier, with the previous camera, that some strays came out ~0.3s off. This suggests that some non-classified tle's are off by 0.3s) This also means that my data from 16 and 19 Sep should be corrected by 0.3s. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@langbroek.org 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 SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com Twitter: @Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
