Hi All,

Looks like that video was taken from this observatory location:

http://en.wikipedia.org/wiki/Pistoia_Mountains_Astronomical_Observatory

44d 03' 47" N (44.06306)
10d 38' 15" E (10.6375)

Based on these coordinates, and assuming a date/time of 8 February 2011
23:24:00 UT, the starting and ending coordinates of the bolide were:

Start: Az 229, El 28
End: Az 227, El 17

Unfortunately, you can't go far in this direction (about 40 km) before
you are over the Ligurian Sea. If the terminal burst was at, say 20 km
altitude, then this would have been 64 km away (i.e. wet). The only
hope is if the terminal burst was at very low altitude. For instance,
for a 12-km burst, the distance is 39 km -- right on the coastline
south of Viareggio.

Hi Dirk,

In that top video, the bright blue star right of center is Sirius. The
dimmer star
at top center is Procyon. The third bright star at the right side (above
the
bolide) is Betelgeuse. If you look very closely, you can see the 3 belt
stars
of Orion, and the bolide passed just to the left of them. Wherever this
camera
is located, the bolide terminated at a bearing of around 240 degrees
(i.e. WSW).
I can give a more precise azimuth once I know the camera's location.
