They refer to the leading bright object in the train. They were not measured with Tangra (the software I usually use for astrometry on my video observations) as that got too confused by so many bright objects. Rather, I stacked a number of frames and measured them manually in AstroRecord. The points above hence might be less accurate than my data usually are. Below is a *VERY CAUTIOUS* orbit estimate, based on adjusting my initial search elset (http://www.satobs.org/seesat/May-2019/0193.html) to the two datapoints, mainly by finding a matching Mean Motion and inclination: STARLINK TRAIN 1 70002U 19999A 19144.94244262 0.00000000 00000-0 00000+0 0 00 2 70002 53.2862 172.0411 0001500 47.9022 312.2115 15.45905383 01 - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Sat May 25 2019 - 08:01:05 UTC
