Yesterday's message that I had updated my decay watch page at 

      http://www.wingar.demon.co.uk/satevo/dkwatch/

did not get propagated on SeeSat-L - I hope this fares better.

Today's update has been made after the probable decay of Sputnik 99 but
before SpaceCom's final decay notice for this. My current analysis
suggests a decay near a southbound equator crossing S of Sri Lanka
in the Indian Ocean at Jul 29 17:36 UTC +-90m. My prediction for the
final elset is:
Sputnik 99       0.3  0.0  0.0  9.0 d 0.28       130 x 124 km
1 25685U 99015C   99210.70290655  .52449767  34018+1  28000-3 0 91865
2 25685  51.6613 112.0239 0005093 253.4030 106.5410 16.54710394 16635
One or more official elsets may yet appear. Congrats to ed Light on the
late obs of this.

SpaceCom has issued the first decay notice for Mir debris NJ, one of two 
newly catalogued Mir debris objects. My preliminary decay estimate is
for July 31 08:13 UTC +-1d.
