Cees Bassa, Russell Eberst, Kevin Fetter, Alberto Rango, Greg Roberts, Scott Tilley, Peter Wakelin, Mike Waterman and Brad Young, contributed observations used to update the following orbital elements. Alberto made another observation of USA 186 in its post-manoeuvre orbit on 2012 Jul 20 UTC. The object he reported as a possible USA 186 on Jul 21 is 79050A / 11389. Here is a revised rough TLE of USA 186: USA 186 1 70000U 12202.81993812 .00028563 00000-0 24691-3 0 07 2 70000 97.8982 264.8777 0540793 82.7763 283.4575 14.77988962 09 On 2012 May 21 UTC, Cees observed an UNID that Mike McCants suspected was one of the three Helios satellites in "secret" orbits. Two of the three have since been identified; therefore, leaving Helios 2A (04049A / 28492) as the likely ID. If so, then it may be found within several minutes of the time predicted by this TLE: Helios 2A 1 70001U 12142.07122759 .00000198 00000-0 37920-4 0 07 2 70001 98.1288 78.2068 0003000 29.3429 330.7941 14.63820000 00 STPSat 2 HAPS 1197 X 1429 km 1 37229U 10062H 12203.90628808 .00000012 00000-0 46994-4 0 03 2 37229 72.0083 247.0225 0150624 345.2420 14.4266 12.86544419 02 Arc 20110120.24-0721.92 WRMS resid 0.024 totl 0.012 xtrk IGS 7A 509 X 511 km 1 37954U 11075A 12204.16527468 .00000439 00000-0 21897-4 0 00 2 37954 97.5141 275.8753 0001032 285.9370 74.1750 15.17613015 08 Arc 20120712.15-0722.17 WRMS resid 0.011 totl 0.010 xtrk Elisa W11 673 X 688 km 1 38007U 11076A 12204.19785342 .00000257 00000-0 50000-4 0 07 2 38007 98.1589 277.7827 0010673 128.4657 231.7505 14.63075705 01 Arc 20120716.87-0722.21 WRMS resid 0.038 totl 0.019 xtrk Elisa E24 679 X 682 km 1 38008U 11076B 12203.92431661 .00000333 00000-0 64983-4 0 00 2 38008 98.1602 280.1035 0001765 335.2218 24.8899 14.63073346 06 Arc 20120711.13-0721.93 WRMS resid 0.016 totl 0.012 xtrk Elisa W23 680 X 681 km 1 38009U 11076C 12204.19801327 .00000411 00000-0 80102-4 0 09 2 38009 98.1614 277.7833 0001141 117.1885 242.9433 14.63076248 04 Arc 20120611.1-0722.21 WRMS resid 0.039 totl 0.022 xtrk Elisa E12 676 X 684 km 1 38010U 11076D 12203.92446726 .00000398 00000-0 77707-4 0 00 2 38010 98.1669 280.1144 0005493 124.9985 235.1733 14.63074222 07 Arc 20120711.88-0721.93 WRMS resid 0.022 totl 0.014 xtrk USA 236 35774 X 35801 km 1 38466U 12033A 12203.01624213 .00000000 00000-0 00000-0 0 06 2 38466 4.9083 274.3890 0003261 178.3710 181.8501 1.00272806 05 Arc 20120716.82-0721.96 WRMS resid 0.003 totl 0.002 xtrk USA 237 r 34153 X 35845 km 1 38529U 12034B 12203.10301136 .00000000 00000-0 00000-0 0 03 2 38529 3.5723 299.3955 0204457 197.3089 162.3369 1.03154173 05 Arc 20120719.93-0721.97 WRMS resid 0.003 totl 0.003 xtrk Ted Molczan _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
