Leo, I have been working with Planet and JSpOC/18SPCS and JSpOC released OBJECT CA TLE earlier today. We have confirmed it is FLOCK 2K-06. We still don’t have any data for the rocket body. - TS Dr. T.S.

In the S&T article they say Mayak is 2017 042F 42830, but this has not shown up on Space-Track as have severeal of the other payloads. Also missing is object CA and the Fregat upperstage object CB. The latter was deorbited after releasing the payloads some 5-6 hours in the flight and decayed over the Indian Ocean.

See the article on Spaceflight101.com<http://Spaceflight101.com> with 2 video's and photo's. This is unlike the Iridiums-1 that had a stable orientation and reflect the sunlight from the antennae panels in a small path over the earth. As MAYAK would be rotating in all 3 directions I think the reflections will spread out over the earthsurface and one must be lucky to see them. The video on Spaceflight101.com<http://Spaceflight101.com> suggest otherwise. But only real observations could clarify that. I have seen another source (that I can't find this fast) mentioning that Mayak would actually be 3-axis stabilized for the first 3 or 4 weeks after launch, i.e. like an Iridium. After this, they will let it tumble (but it will decay fast). It is a pitty that the people behind Mayak aren't more forthcoming with information about their spacecraft operations, certainly giving the media hype they created about "the brightest object in the sky". Their website gives very little useful information about the operational phase of the satellite. - Marco PS: ah, found a source (not the one I had seen earlier) mentioning the 4 week stable orientation mode: http://www.skyandtelescope.com/astronomy-news/bright- moon-new-satellite-mayak-light-sky/ ----- 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-l _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Tue Jul 25 2017 - 18:32:07 UTC
