SatEvo decay list #76 (issued 1999 May 2)
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 June 15 (as in my previous list), although some larger and/or more
interesting decayers are included beyond that date. In general, decay
dates have slipped since last time and a number of objects, mostly
debris, have dropped off the list. Several recently catalogued debris
objects from the Cosmos 2053 Tsyklon-3 rocket seem likely to decay
within the coming weeks; to date, these have too few published elsets
for me to predict their decay.
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.
