Thanks Ed and Igor, CalSky, under high magnification, shows the tracks of SJ 12 and SJ 6H completely overlying one another. Looks like a rendezvous.

Latest elsets with epoch 329.78 indicate rather slow approach, 1 km per orbit. > If these are reliable, and if further maneuvers not made since then, Shijian-12 would not achieve the target in the first window of visibility from China which is from 23:48 till 03:05 UTC or so. Maybe the final approach is to be conducted in the second window of visibility on November 26, 10:37-15:26 UTC. > > Sincerely, > Igor Lissov > _______________________________________________ > Seesat-l mailing list > http://mailman.satobs.org/mailman/listinfo/seesat-l _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
