I have again updated my Decay Watch page at 

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

with updated predictions for #25780, the Iridium 14A Smart Dispenser.
This decay has slipped to July 25 09:17 UTC by my current estimate, when
it would be northbound over the S Atlantic.

Two Mir debris objects have been catalogued, presumably released during
yesterday's EVA. I do not know whether either object is observable, but
both appear to be rapid decayers and have been added to my SatEvo
dklist. Current elsets are...
Mir deb NG                                       339 x 335 km

respectively.
