Hi all, With the new postponement of the ZUMA launch to January 8th (January 7th local time), here are new elset estimates for an assumed 395 x 400 km orbit for various launch times: ZUMA launch 2018-01-08 01:00:00 UT 1 70014U 18999A 18008.04166667 .00000000 00000-0 00000-0 0 04 2 70014 049.9992 016.5689 0007377 049.0381 324.6717 15.55741113 03 ZUMA launch 2018-01-08 02:00:00 UT 1 70015U 18999A 18008.08333333 .00000000 00000-0 00000-0 0 05 2 70015 049.9992 031.6099 0007377 049.0381 324.6717 15.55741113 07 ZUMA launch 2018-01-08 03:00:00 UT 1 70016U 18999A 18008.12500000 .00000000 00000-0 00000-0 0 08 2 70016 049.9992 046.6510 0007377 049.0381 324.6717 15.55741113 02 ZUMA launch 2018-01-08 03:30:00 UT 1 70017U 18999A 18008.14583333 .00000000 00000-0 00000-0 0 01 2 70017 049.9992 054.1715 0007377 049.0381 324.6717 15.55741113 04 With this new postponement, targetting the orbital plane of USA 276 has become viable near the end of the 1:00 - 3:30 UT launch window. The orbital plane of USA 276 passes over the launch site near 3:38 UT on January 8th. - 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 Fri Jan 05 2018 - 07:58:31 UTC
