I observed Polar r last night as follows: Site 2707 using 8x50B UTC RA (1950.0) Dec 21:23:51.2 05 34 50 +21 10 34 Mag 4 st 21:24:10.4 06 16 20 +14 33 07 I make this 46s late with respect to my SatEvo orbit evolution given in my previous "Decay update" posting, but only 3s early with respect to a prediction from the latest available OIG orbit (for 96117.43). A SatEvo evolution of the latter orbit, with ndot adjusted to satisfy my observations, results in the following predicted elements: Polar r 1 23803U 96013B 96118.80849307 .02618404 14793-2 74742-3 0 91370 2 23803 85.8980 349.7328 0138070 38.2090 322.7618 16.08098693 9742 Polar r 1 23803U 96013B 96119.05730400 .02735547 16716-2 75883-3 0 91373 2 23803 85.8975 349.5779 0132895 37.1536 323.7572 16.09430225 9782 Polar r 1 23803U 96013B 96120.05034205 .03406154 30665-2 81320-3 0 91377 2 23803 85.8953 348.9560 0109838 32.9201 327.7594 16.15461905 9944 Polar r 1 23803U 96013B 96121.03917085 .04756966 69415-2 78971-3 0 91375 2 23803 85.8924 348.3304 0080569 28.6631 331.7749 16.23392376 10101 Decay is now predicted for May 1.2.
