Photometry on my video images of the tumbling NOSS 3-4 rocket (2007-027B) yields a period of 13.78 seconds on 18 April 2017, 21:47 UT, with a variation of 1.5-2.0 magnitude. Diagram is here: https://twitter.com/Marco_Langbroek/status/854704408994689024 Obtained with a WATEC 902H + 1.4/85 mm lens, GPS time inserter, video analysed with TANGRA, period fitted with PAST. The gap in the diagram is due to repositioning the camera. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4355 (Cronesteyn): 52.13878 N, 4.49937 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Wed Apr 19 2017 - 09:42:34 UTC
