I awoke to a message from Joseph Remis with news that the re-entry of 2014-088B / 40363 had been seen from the western
U.S. and Canada. It was stage 3 of the CZ-4B rocket that launched Yaogan Weixing 26 on 2014 Dec 27 UTC.

USSTRATCOM's apparently final TIP message, issued at 11:15 UTC, reports the decay at 5:54 UTC +/- 7 min, near 42.3 N,
111.6 W. That corresponds to descent to 10 km, the approximate toe of the debris footprint (should any have survived to
impact Earth). Based on the sightings, the final descent was farther north, well into Canada, but within the stated time
uncertainty.

As I write, more than 140 observations have been reported to the AMS site:

The object was north-bound, descending from a 97.3 deg orbit. There are confirmed sightings from Arizona, Utah, Nevada,
Wyoming, Idaho, Oregon, Washington, Montana, British Columbia, Alberta. The most southerly observation I have noted so
far was from Scottsdale, Arizona; the most northerly from Didsbury, Alberta. That spans nearly 3000 km of the descent.

I have plotted a large sample of the AMS sighting locations, along with the ground track of 14088B:

Joseph provided a link to a video:

No doubt there are many more.

Today's re-entry is number 251 in my table of visually observed natural re-entries:
