SatEvo decay list #86  (issued 1999 October 23)

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

In most cases, 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 November 30, 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. I also maintain a large file,
satbase.tle, containing recent elsets for more than 8,000 satellites.
This is available in zipped form from the same address.

I publish my own and SpaceCom's updated predictions for the larger 
decayers during their final days on my Decay Watch page at
               http://www.wingar.demon.co.uk/satevo/dkwatch/
This includes my predicted elsets for these objects.

Notes

1. SpaceCom has yet to confirm this decay.

2. #24445 = 94- 29 TB was listed as decaying on September 30 in my
previous decay list. After a gap of three days, however, further 
appeared and showed it on the brink of decay.

3. The re-entry of #12134, Molniya 3-14 r2, was observed from the 
Johannesburg/Pretoria area of South Africa at midnight UTC
(02:00 local time) on October 22/23. The sightings were of a very 
bright object followed by 8-10 lesser objects. I also understand that 
a traffic officer secured some video footage and that this has 
appeared on TV. Thanks to Claire Flanagan of the Johannesburg 
Planetarium for connecting the reports she received with the
prediction of this decay on my Decay Watch page.
