		<description>I&#039;ve also been following Wonders of The Universe and getting into astronomy because of that. The idea of collecting piece of meteorite and holding a piece of rock that comes from outer space is just mind boggling.</description>

		<description>I&#039;m only just getting into astronomy after watching Proff&#039; Brian Cox UK TV series (wonders of the universe). I didn&#039;t see the above but I have seen the video - Awesome!

I&#039;ve also just downloaded the &#039;Star Walk&#039; app on my iphone, (if you haven&#039;t seen it give it go - it&#039;s excellent).

Any tips for a budding enthusiast are greatly appreciated.

Cheers,</description>

		<description>Haven&#039;t seen the episode yet, but we did have the opportunity to work with the Meteorite Men team as they were trying to locate pieces of that meteor. Time to search for the episode online and check it out!</description>

		<description>Did anyone else see the Meteorite Men &quot;Dugway&quot; show?  They got permission to hunt on the Proving Grounds with military chaperones.  The searched two parts of the base and on the southern perimeter.  No meteorites were found.  There has to be pieces out there somewhere!  ;)</description>

		<description>Thanks for checking in. 

We haven&#039;t heard any updates of people finding any pieces of the meteorite on the ground. If we do hear of something, we&#039;ll be sure to let people know.</description>

		<description>Seth,
Is there a map available showing the estimated ground track of the Nov 18
fireball?  I&#039;ve been looking at radio observations from USU&#039;s Bear Lake
Observatory and there are some oblique signal readings that would be
consistent with a meteor trail possibly in the 90-100 km altitude range
in northwest Utah (Utah side of where Nevada and Idaho come together) at
the time of the fireball.  These are rather sloppy measurements, but it
sounds like they might be consistent with the fireball path.  Any information
would be appreciated.

		<description>Adam,

Super-bright meteors are amazing and memorable things to see. One of the most common things that happen when people watch a fireball is that they underestimate the distance and elevation of the meteor.  

For example, there was a daytime fireball visible in 2001 that was widely reported to us as having landed in the foothills above Bountiful, when in fact the meteor was reported from Idaho Falls to Lake Powell, and probably came down somewhere near the Utah-Colorado border.

The point I&#039;m making is that our brains are easily tricked.

Most meteors (&quot;shooting stars&quot;) are created by bits of rock in space that are generally smaller than a grain of rice entering our atmosphere and vaporizing in a flash of light from the extreme heat generated by the encounter.  These events typically occur 30-40 miles above the ground.

The fireball seen at 12:07 AM on November 18th was probably bigger than a kitchen stove.  The intense light it created as it vaporized was reported from as far east as Rifle, Colorado, as far north as Malad, Idaho, as far west as Reno, Nevada, and as far south as Prescott, Arizona.

Check out a recent news story by KSL-TV, an in it you&#039;ll see some amazing video from a dashboard camera mounted on a police car in Grand Junction, Colorado.  Here&#039;s the link: 

http://www.ksl.com/?nid=148&amp;sid=8858815

For this fireball to be seen from a police cruiser in Colorado, more than 200 miles to the east of Salt Lake City, and Frisco Peak near Milford, and cast the shadows that were recorded by security video cameras along the Wasatch Front, it had to be at least 30 miles above the ground.  

We triangulated using multiple location reports and back-tracing shadow information obtained from security camera videos. From this we are fairly confident that the meteor entered Earth&#039;s atmosphere 80 - 120 miles to the west of Salt Lake City, probably in the vicinity of the Deep Creek Mountains.

I hope this helps.

Keep your eyes on the skies &amp; all the best,

Seth</description>

		<description>I saw one of the metorites and believe it was much closer than the accounts I have read about. I would be willing to bet I was within 200 yards from one that came in on a pretty sharp angle. Sharper than any of the pictures I have seen so far. I would also say it was about 200 feet off the groud before it went out. It lasted for 6 - 8 seconds. The reason I think it was so close was because of how quickly I passed it. I would think if it were further away, I would have almost remained fixed in my window. Also I could dictinctly see the detail and motion of the flame trail.

This was near the weave in Farmington.

I would certainly like to talk to someone about it and see if it is possible to find it.</description>

		<description>UPDATE:

The video from the Frisco Peak Observatory operated by the University of Utah was a view to the NORTH.  That&#039;s 180 degrees from where I&#039;d first thought it was!

I stand corrected!

For the Frisco Peak camera to be showing a south-to-north motion, while in Salt Lake City and points nearby there were reports of a north-to-south motion, that means that the meteor itself must have been coming it at quite a steep angle from somewhere more-or-less midway between the Wasatch Front and Milford.

This also makes sense of the three second duration of the event.  Shallow angles generally mean longer periods of visibility. Three seconds is pretty quick for a fireball of this brightness.

We&#039;ll be out and about in the Salt Lake Valley for a little while tomorrow taking measurements to understand what security cameras were seeing and try to get a better fix.  

When we know anything interesting we&#039;ll share it here.

Pretty cool stuff!</description>
