Our Strange Sky: Meteor Streaks Huntsville, Scottsboro.

It was bright.

It was shiny.

It skipped off the skin of the Earth.

Meteor!

SCOTTSBORO, AL (WAFF) – On May 18th, NASA cameras at the Marshall Space Flight Center and Walker County Science Center near Chickamauga, Georgia tracked the entry of a large meteor estimated to weigh some 60 pounds over northeastern Alabama.

This meteor was first picked up at an altitude of 47 miles over northwest Huntsville, moving at a speed of 8 miles per second towards the southeast. It was last visible northeast of Gurley at an altitude of 23 miles.

The meteor was quite bright, with an intensity rivaling that of the waxing crescent Moon (in astronomical terms, it was about visual magnitude -8.3). Calculations automatically performed by the tracking software indicates that this interloper was from the main asteroid belt, moving in an orbit which takes it more than three times Earth’s distance from the Sun.

Observe HQ video and non-altered imagery over on WAFF’s webhouse.

They think pieces of it may have landed north of Woodville and Scottsboro. If any of you find it, NASA would love a piece of it.

If you think you may have seen the meteor, call Dr. Bill Cooke at 256-544-9136 begin_of_the_skype_highlighting              256-544-9136      end_of_the_skype_highlighting email him at william.j.cooke@nasa.gov.

Worth noting: it might not be a bad idea to alert the Meteorite Men if any of you sky-watchers find this cold piece from the heavens.

Update: NASA still wants your help finding the meteorite.

Texas Fireball Explained: and the World “Exploded in Green!”

In an effort to recapture my fascination with the Internet, I denied myself the pleasures of Twitter(for the most part) and endeavored to finish other things that needed doing. Things like sunshine and disarming traps making the apartment, once again, guest receivable. As Twitter more addictive than a line of strippers or bags of cocaine dancing around poles, I lurked outside the great internet social party. That’s when I learned of the fireball over Texas.

What you just saw was not satellite debris. The high speed of the fireball in the News 8 video is typical of a natural meteoroid hitting Earth’s atmosphere at tens of km/s. Orbital debris, on the other hand, should crawl across the sky at a fraction of that speed. Astronomer Bill Cooke of NASA’s Meteoroid Environment Office has reviewed the video and confirms “it’s a natural meteor, definitely.” According to his analysis, the source of the fireball was a meter-class asteroid traveling at about 20 km/s.

Fireball mania started on Friday the 13th, around 10 p.m. EST, when people in central Kentucky heard loud booms, felt their houses shake, and saw a fireball streaking through the sky: reports. “The world appeared to explode–in green!” said one eyewitness. Once again, this appears to be a natural event caused by a meteoroid. Iridium 33 and Kosmos 2251 collided at a speed of about 10 km/s or 22,000 mph. None of the surviving fragments should have been big enough to shake houses in Kentucky. Furthermore, US Space Command, which monitors objects in Earth orbit, has not announced a reentry over Kentucky on Feb. 13th.

One day, SpaceWeather.com, you will learn of permalinks. On that day, I shall welcome you into post 1990s internet society.
