    SatEvo decay list #114 (issued 2001 March 24)
    
    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://www2.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 2001 May 20, 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 the ISS, the Shuttle and all newly 
    launched and/or catalogued objects. I also maintain a large file, 
    satbase.tle, containing recent elsets for some 8,400 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. Although my policy is to exclude from this list objects that 
    are de-orbited intentionally (eg Shuttle, Soyuz, Progress), I make 
    an exception for Mir. The "decay" time above corresponds to the 
    observed re-entry phenomena over Fiji, with ocean impact probably 
    just before March 23 06:00 UTC.
    
    3. Following my warning of its imminent decay in my previous Decay
    List, #26538 = Cosmos 2372 was manoeuvred higher and no longer 
    appears in the above list.
    
    4. Thanks to Michael A. Earl of the Space Surveillance Research and 
    Analysis Laboratory, Royal Military College of Canada, Kingston, 
    Ontario, for the "heads up" regarding several of the objects that 
    are decaying from Molniya-type orbits.
