In the absence of Harro Zimmer and Alan Pickup, I will briefly step
in......

Object 26406 - BIRD-RUBIN/SL-8 R/B
    Forecasted by USSPACECOM to decay 30-Aug 02:28.

    Using special perturbation scheme (similar to Harro's), my forecast
is 30-Aug-01:38 UT at the 115 km altitude pt.
    What is interesting is groundtrack of last predicted orbit......
          Object north-going passes just to the East of London UK at
01:02:30 UT
                     (potential sighting if early demise!!!) (48 deg
elev at 37 deg az)

          If object lives another 1/2 orbit, it passes south-going
directly over South Island NZ at 01:44 UT
