Report time: 11:15 UTC 1964-049D (#869) Cosmos 41 SCC'S FINAL REPORT -prepared April 09,03:30 UTC - shows the decay on: 09 April, 03:17 UTC +/- 07 minutes (61.0°N, 14.0°E) ascending over Sweden. MPM + REENTRY delivered with the last ELSET 04100.061... and a special correction for the ballistic coefficient (SFX 095, ap 030) the decay on: 09 April, 03:20 UTC +/- 13 minutes (63.97°N, 35.36°E, Altitude 10.0 km) descending over the Barents Sea. Remarks: A difficult decayer. My last forecast (April 08, 19:00 UTC) was within 02 minutes in excellent agreement with SCC'S following 06 HOURS BEFORE DECAY and 02 HOURS BEFORE DECAY messages - prepared April 08, 22:42 UTC and April 09, 02:40 UTC. Shortly after this SCC released on April 09, 02:48 UTC a new forecast that showed the decay one rev earlier. With a special program I compared the ELSET 04099.72668531 (17:27 UTC) with the following reliable and final ELSET 04100.06144494 (01:29 UTC).The time of the closest approach was April 08, 18:37 UTC with a Delta of 154.653 km. Until the final ELSET epoch Delta increased to 2837.236 km ! This is an indication for a "catastrophic" decay. Also interesting: The predicted perigee times and altitudes near the decay: 04099.726... April 09, 03:15:55.47 UTC - 99.897 km 04100.061... April 09, 03:05:07:55 UTC - 89.331 km Harro Harro.Zimmer@t-online.de Berlin, Germany ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
