SatEvo decay list #90 (issued 1999 December 26)
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 February 5, 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. I also maintain a large file,
satbase.tle, containing recent elsets for more than 8,000 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.

Notes
1. SpaceCom has yet to confirm this decay.
2. The estimate for Mir's decay is on the (probably unrealistic) basis
that there are no further manoeuvres.
