That time, 04:04 UTC, puts it off the Irish coast, but on track with the other predictions

The US no longer considered for the area of fly-over?

NASA has an update too.

As of 7 p.m. EDT on Sept. 23, 2011, the orbit of UARS was 90 miles by 95 miles (145 km by 150 km). Re-entry is expected between 11 p.m. Friday, Sept. 23, and 3 a.m., Sept. 24, Eastern Daylight Time (3 a.m. to 7 a.m. GMT). During that time period, the satellite will be passing over Canada, Africa and Australia, as well as vast areas of the Pacific, Atlantic and Indian oceans. The risk to public safety is very remote.

Im think London has one more chance to see something at 1:06 low in the north so plan to give it one last chance viewing then.

Updates in a wee while - but that time is probably around the best predicted time.

Hi All,

is their any new entry period than 03:16 UTC ± 5 hours?

So that mean 22:16UTC-8:16UTC? At now 23:15UTC and current Orbit number 10916. If I count correctly with 89minute period and that was close to here about 40minutes ago (over Polland):

About: nr.10917 0:04UTC (above my Budapest, Hungary location), nr.10918 1:33UTC (Between me and Milan:) after that point we (most part of Europe) will lose all posibilites to see samthing.

But Milan dont need to worry: just cycle number +14 can pass over North italy and Hungary) but that time 14*89min=20,76h later he must be down.

I am right, or any misscounting? Also many thank for more precise TLE infos (that is how I found this homepage:)

Good luck: Jackson
