    decay notices are being issued for two objects at present. The following 
    is a summary of the latest updates to my Decay Watch page.
    
    _____________________________________________________________________
    Object: #27485 = 92- 41 F = Insat 2A Ariane 44L debris F

    Note: The reported Radar Cross Section for this debris object is
    2.2 m^2. This enters eclipse at a height of about 270 km while
    northbound near 5.2 deg S in the evening. eclipse exit occurs at
    about 1,000 km near northern apex (7.3 deg N) at ~04h local time.
    The predicted elsets are very uncertain.

    Note: This is sunlit all around its orbit, being best placed at mid-
    to high-northern latitudes in the morning twilight.
