    1985-105A (#16235) Cosmos 1701
    
    OIG showed today (UTC) the decay of Cosmos 1701. SPACECOM hasn't issued any
    TIP message. There are five peculiar ELSET'S for these three days:
       May 05  Mean Motion: 6.344...     Eccentricity: 0.4762...
       May 07    "    "     7.213...          "        0.4217...
       May 10    "    "    15.829... !!       "        0.0371...  !!
    I don't see a "normal" explanation for this big jump between May 07 and 
    May 10. It looks like a "catastrophic" event. 
    The perigee altitude on the last epoch time - 1130.5628... - was 80.60 km.
    Based on the last two ELSET'S MPM + REENTRY delivers the decay on
                          10 May, 13:54 UTC +/- 17 minutes (28.11S, 353.90E)
    on a descending pass over the South Atlantic. It is also possible that the
    satellite survived for another rev. OIG reported:" Decayed 2001/05/11"
