BIG KaaaaaaBOOM



The BIG KaaaaaaBOOM Tuesday night over Michigan NASA says was a meteor about 6 feet in diameter.



It exploded in the air with the power of 10 tons of TNT, according to Bill Cooke of NASA's Meteoroid Environment Office, the Associated Press reported.



The American Meteor Society has so far received more than 355 fireball sightings from six U.S. states and Ontario, Canada. NASA Meteor Watch used these reports to map the meteor’s path.



The meteor disintegrated into lots of smaller pieces known as meteorites as it flew through the sky. These scattered across the ground, waiting to be found.



Robert Ward, a freelance planetary field scientist, found his first meteorite on a frozen Michigan lake at 9.50 a.m. Thursday, according to the Detroit Free Press.



Holding the biggest of his meteorites, Ward told the newspaper: “Two days ago, this was hundreds of thousands of miles past the moon, and now I’m standing here holding it in my hand. It’s been a real good day.”



Ward and his team used scientific data to hunt down the meteor fragments. “We had really good data on this one,” Ward said, according to the Detroit Free Press. “The seismic data lined up with Doppler data and the witness data. Everything came together on this one.”

Iron ore is the most common meteor-wrong. Magnetite especially is very magnetic (hence its name) and hematite may or may not be mildly magnetic. Both these minerals may possibly be distinguished from meteoritic material by a characteristic known as 'streak'. You can test the streak very simply. If you take a common ceramic tile, such as a bathroom or kitchen tile, it has a smooth glazed slide and an unfinished dull side which is stuck to the floor/wall when installed. Take the sample which you think is a meteorite and scratch it quite vigorously on the unglazed side of the tile

If it leaves a black/gray streak (like a soft leaded pencil) the sample is likely magnetite, and if it leaves a vivid red to brown streak it is likely hematite. A stone meteorite, unless it is very heavily weathered will not normally leave a streak on the tile.

You say that you don't have a ceramic tile? You can use the bottom of an ceramic coffee cup or you can also use the inside of your toilet tank cover. (the heavy rectangular lid on top of the tank) It is very heavy, so be careful.

Yes, this was a biggee. Good thing it broke up into tiny fragments or it could have caused a lot of damage on impact. There are so many cameras around now that nothing is missed.

Fortunately the kaboom happened before it hit the ground

From the sounds of it a little bit bigger than a refrigerator.

It would have been an even BIGGER KaaaBOOM had it hit the ground, however, stony type meteors lack the structural integrity to withstand the forces of entry into the earth's atmosphere fortunately for us on the ground.

meteors are cut and an acid etch to look for distinguishing streaks pattern .

I've seen some beautiful pieces after they have been cut and polished

From the looks of things Those of us REAL GUYS who have just one profile and follow the rules are going to have to stand up and band together against the negative few with a multitude of FAKE PROFILES. Keep our messages positive, without negative attacks and those REAL MEMBERS of OP will stand with us and support us.
