SatEvo decay list #63  (issued 1998 October 7)

This list of my satellite decay (re-entry) predictions and analyses 
is again being 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 November 16, 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, the Shuttle, and 
all newly launched and/or catalogued objects.

Note

1. 98- 54 A, the payload of this launch, has also been called Cosmos
2361 though the orbit is distinctly Molniya-like. Perhaps this is a
failed Molniya?
