The latest OIG elset for this object is: Centaur r 6710 x 100 km 1 24666U 96067B 97094.70777550 .75566461 -12660-4 45394-2 0 1954 2 24666 23.7308 128.5807 3378017 296.9146 32.7804 8.97224110 3603 This shows it running 9.0 minutes early with respect to the SatEvo prediction I posted yesterday; not too bad considering that the orbital period had fallen by 23+ minutes during the intervening 26 hours. Again, the published ndot2 term is unrealistically low. A new evolution gives a revised decay prediction for about April 7.1 and the following predicted elsets: Centaur r 6103 x 101 km 1 24666U 96067B 97095.03457401 .70533174 89730-1 39599-2 0 91846 2 24666 23.6782 127.3670 3165782 298.6646 33.1603 9.40585586 267 Centaur r 5100 x 101 km 1 24666U 96067B 97095.54553096 .86446431 12263+0 41479-2 0 91840 2 24666 23.6448 125.8245 2784004 301.3546 34.3309 10.20491969 314 Centaur r 4104 x 101 km 1 24666U 96067B 97096.01566186 1.10018329 22707+0 44304-2 0 91840 2 24666 23.6126 124.1814 2360118 304.2213 35.5899 11.11718914 365 Alan -- Alan Pickup | COSPAR site 2707: 55d53m48.7s N 3d11m51.2s W 156m asl Edinburgh | Home: alan@wingar.demon.co.uk +44 (0)131 477 9144 Scotland | Royal Observatory: A.Pickup@roe.ac.uk +44 (0)131 668 8224
