I continued my coverage of KMS-4 and its UNHA-3 r/b (2016-009A & B) on March 3 and March 5. As expected, the flash period of the rb (2016-009B) is (very) gradually changing, at a rate of about 0.01 second a day. I measured 2.43 seconds on March 3 and 2.45 seconds on March 5. More on this here, including a fine 10-second exposure with four flashes: http://sattrackcam.blogspot.nl/2016/03/the-tumble-period-of-unha-3-upper-stage.html On popular request, I have also included a brief description on how I process and analyse the images to get to these results at the end of that post. - 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 Mon Mar 07 2016 - 06:19:40 UTC
