Update #6

Wed, 21 Sep 2011 04:00:29 AM GMT+0800

As of Sept. 20, 2011, the orbit of UARS was 127 mi by 140 mi (205 km by 225
km). Re-entry is expected Sept. 23, plus or minus a day. It is still too
early to predict the time and location of re-entry. Predictions will become
more refined over the next two days.
