Based on triangulation of multiple cameras, Italian astronomers have computed a terminal burst altitude of 30.3 +/- 1.2 km. So mainland Italy is out. However, yesterday I was amused to discover that when I combine the terminal burst altitude information with my estimate of the terminal burst azimuth, it ends up right over the only spit of land within a 20-mile radius: tiny Isola di Gorgona (area less than 1 square mile). Of course, meteorites aren't necessarily found directly under the terminal burst location -- there is still forward momentum of the fragments, plus wind drift. But at this point it's not impossible that some fragments might have ended up on that island, which would be an incredible stroke of luck. Note that I've renamed the thread to Italian bolide from superbolide; the magnitude (-10.9 +/- 1.1) was far below the threshold for a superbolide. --Rob -----Original Message----- From: meteorite-list-bounces at meteoritecentral.com [mailto:meteorite-list-bounces at meteoritecentral.com] On Behalf Of M come Meteorite Sent: Wednesday, February 09, 2011 9:33 PM To: meteorite-list at meteoritecentral.com Subject: Re: [meteorite-list] Italian Superbolide 8FEB2011 I doubt, Italy zones is not type USA desert or city's, we are under control the coordinates for calculate where is fall. Only to hope is not fall in the sea matteo Received on Thu 10 Feb 2011 02:05:50 PM PST |
