##Cosmos 1278 was another spacecraft of the Cosmos 862-type to experience a fragmentation 1986 early December. Spacecraft had apparently been inactive since early 1984. Additional fragments may exist, but surveillance for small objects in this orbit is difficult.

*Cosmos 1286 was the ninth spacecraft of the Cosmos 699-type to experience a fragmentation. The spacecraft had been in a regime of natural decay for more than six months at the time of the event 1982 Sep 29 at 05:20 UT near 51ºN 80ºE. The low altitude and high drag conditions made determination of the precise breakup time uncertain. The breakup or a precursor event may have occurred earlier on 29 September 1982. Most fragments decayed before being officially catalogued.
