SatEvo decay list #74 (issued 1999 April 4) 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 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 1999 May 31, although some larger and/or more interesting decayers are included beyond that date. 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. # Designation Name ----- Decay (1999) ----- Predicted Actual? 25426 94- 29 ADS STEP-2 Pegasus deb March 22 25658 99- 13 B AsiaSat 3S Proton r March 22.59 25607 99- 1 C MPL Delta 2 r1 March 23.08 24693 94- 29 ABB STEP-2 Pegasus deb March 24?
