SatEvo decay list #71 (issued 1999 February 20)
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 April 15, although some larger and/or more
interesting decayers are included beyond that date. Drag rates
increased sharply in the past week as solar activity reached its
highest level of the current solar cycle.
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.
