SatEvo decay list #74  (issued 1999 April 4)

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 May 31, 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.
