SatEvo decay list #69 (issued 1999 January 19)
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 March 15, although some larger and/or more
interesting decayers are included beyond that date. With drag
rates having been low since my previous list, most decay dates
have slipped.
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.

Notes
1. The predicted (natural) decay of Mir assumes that its orbit
is not boosted again and that plans to de-orbit it about June
are not carried through.
2. No recent elsets.
3. SpaceCom has yet to confirm this decay.
