SatEvo decay list #99 (issued 2000 May 13) This list of my satellite decay (re-entry) predictions and analyses is posted to the satellite observers mailing list, SeeSat-L, and to the Usenet newsgroup sci.astro.satellites.visual-observe. Information about SeeSat-L is available at http://www.satellite.eu.org/seesat/seesatindex.html In most cases, the "Actual?" decay dates are my estimates based on the published orbital element sets ("elsets") over the object's final days. Objects are included in the "Predicted" column if I anticipate their decay by 2000 June 30, although some larger and/or more interesting decayers are included beyond that date. Most decay dates have slipped since my last posting, in line with (temporarily) decreased solar and geomagnetic activity. This and other recent decay lists are available on the WWW via my SatEvo page at http://www.wingar.demon.co.uk/satevo/ Linked from this page are files containing recent elsets for all the Iridium satellites, all the objects in this decay list, plus elsets for other selected objects including Mir, ISS, the Shuttle and all newly launched and/or catalogued objects. I also maintain a large file, satbase.tle, containing recent elsets for more than 8,300 satellites. This is available in zipped form from the same address. I publish my own and SpaceCom's updated predictions for the larger decayers during their final days on my Decay Watch page at http://www.wingar.demon.co.uk/satevo/dkwatch/ This includes my predicted elsets for these objects. # Designation Name ----- Decay (2000) ----- Predicted Actual? 25056 64- 26 J Transit 9 deb April 18?

SpaceCom has yet to confirm this decay. 2. No recent elsets. 3. #25124 (97- 85 B = Early Bird r) was incorrectly identified as #25125 last time. Also #26245, the SESat Proton platform was given the incorrect designation 00- 19 B, when it should have been 00- 19 C.
