Hi all, Using observations from Sep 11 and Sep 14, I have been able to narrow the fit to the brightness variation of 2013-070B, the CZ-3C upper stage from the Chang'e 3 Lunar mission, and obtain a more accurate periodicity. The curve is part of my blogpost here: http://sattrackcam.blogspot.nl/2015/09/the-tumble-periodicity-of-change-3.html I find a periodicity of 423.01 +- 0.03 seconds, peak-to-peak. A nice result, that would not have been possible without the kind help of Peter Starr (MPC Q65) and Krisztián Sárneczky (MPC 461). - 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 Tue Sep 15 2015 - 13:47:08 UTC
