Reports about East Coast meteor flood in, setting off a media scramble

By Alan Boyle, Science Editor, NBC News


A Friday night flash of light in the skies over the East Coast sparked a rash of meteor sighting reports, followed by a mad dash to track down photos and videos of the event.

The American Meteor Society logged more than 300 reports from a region ranging from  North Carolina to Washington to New York to New England to Canada. Hundreds more registered their observations on Twitter.  One Twitter user, known as @Married2TheNite, reported from New Jersey that he saw — and heard — the object pass by.
"It was making almost a hissing noise as it flew brightly overhead," he wrote. "I saw it around 7:55 p.m. EDT."

That time frame meshed with the many other reports. Some witnesses said they saw flashes of green, red and blue as the object streaked past.

The reports were consistent with a fireball — similar to the one that flashed over Russia on Feb. 15, but much, much smaller.


--------------------------------------------------------------------------------

"It's not an incredibly rare event, but it is very unusual to have that many people observe it, and also it was unusually bright," Ron Dantowitz, director of the Clay Center Observatory, told NBC station WDHD-TV in Boston. "These types of meteors happen once or twice a year. The unusual thing is that it was so well observed not so long after sunset."

Bill Cooke of NASA's Meteoroid Environmental Office told The Associated Press that the flash appeared to be "a fireball that moved roughly toward the southeast, going on visual reports."

"Judging from the brightness, we're dealing with something as bright as the full moon," Cooke said. "The thing is probably a yard across. We basically have (had) a boulder enter the atmosphere over the Northeast."

For a while, Twitter buzzed with tweets and retweets highlighting pictures that falsely purported to show the Friday night light — but eventually, bona fide views surfaced. The paucity of honest-to-goodness meteor shots contrasted with the wealth of dashboard videos that came to light after last month's Russian meteor blast.

"The meteor has taught us one thing tonight," Cara Lynch tweeted, "the East Coast needs more dash cameras."

One of the most widely distributed videos of Friday night's flash came from someone who didn't actually see it when it happened. "I wish I would have seen it for real," said Kim Fox, a first-grade teacher from Thurmont, Md.

Fox told NBC News that she checked her security-camera system after hearing about the meteor. At around the time that news reports said the meteor was widely sighted, she saw a bright flash on one of the camera views. She took out her mobile phone, recorded a video of the video, and posted it to her Facebook page. From there, the video went viral on the Web and on TV newscasts.

"The phones have been ringing all night," Fox said.

Did you see the flash? Add your sighting report to the American Meteor Society's log, and tell me about it in the comment space below. Got pictures? Feel free to post them to the Cosmic Log Facebook page.

Update for 1:22 a.m. ET March 23: In one reference, I mistakenly placed Thurmont in New Jersey rather than Maryland. Sorry about that! Also, more video views of the flash have come in. Hopkins Automotive Group posted this flashy security camera video on its Facebook page. There's also this dashcam view from WUSA9 photojournalist Kurt Brooks.

I think NASA owes us an explanation. This can't all be coincidence.

INCOMING!!!!!!



NASA doesn't owe us an explanation... the MILITARY does  because in 2009 they made incoming space rocks [CLASSIFIED]

So we should ask THEM why :P

Yes, indeed; makes one wonder, since life seems to be influenced by sci-fi... in the movie Starship Troopers ( based loosely on the novel by the sci-fi master, Robert Heinlein) the Earth was being bombarded by meteors aimed by the bug-like Arachnids...

also makes me wonder if the powered exo-skeletons ( which Z and I both need  8)) also didn't originate from the same novel, considerig the cap troopers of the Mobile Infantry wore suits of powered armor that functioned not only as a space suit by also transformed the wearer into a one man tank that could jump a half mile at a time...

Military Hush-Up: Incoming Space Rocks Now Classifiedby Leonard David, SPACE.com's Space Insider ColumnistDate: 10 June 2009 Time: 05:35 PM ETinShare.6
 
For 15 years, scientists have benefited from data gleaned by U.S. classified satellites of natural fireball events in Earth's atmosphere – but no longer.

A recent U.S. military policy decision now explicitly states that observations by hush-hush government spacecraft of incoming bolides and fireballs are classified secret and are not to be released, SPACE.com has learned.

The satellites' main objectives include detecting nuclear bomb tests, and their characterizations of asteroids and lesser meteoroids as they crash through the atmosphere has been a byproduct data bonanza for scientists.


The upshot: Space rocks that explode in the atmosphere are now classified.

"It's baffling to us why this would suddenly change," said one scientist familiar with the work. "It's unfortunate because there was this great synergy…a very good cooperative arrangement. Systems were put into dual-use mode where a lot of science was getting done that couldn't be done any other way. It's a regrettable change in policy."

Scientists say not only will research into the threat from space be hampered, but public understanding of sometimes dramatic sky explosions will be diminished, perhaps leading to hype and fear of the unknown.

Incoming!

Most "shooting stars" are caused by natural space debris no larger than peas. But routinely, rocks as big as basketballs and even small cars crash into the atmosphere. Most vaporize or explode on the way in, but some reach the surface or explode above the surface. Understandably, scientists want to know about these events so they can better predict the risk here on Earth.

Yet because the world is two-thirds ocean, most incoming objects aren't visible to observers on the ground. Many other incoming space rocks go unnoticed because daylight drowns them out.

Over the last decade or so, hundreds of these events have been spotted by the classified satellites. Priceless observational information derived from the spacecraft were made quickly available, giving researchers such insights as time, a location, height above the surface, as well as light-curves to help pin down the amount of energy churned out from the fireballs.

And in the shaky world we now live, it's nice to know that a sky-high detonation is natural versus a nuclear weapon blast.

Where the space-based surveillance truly shines is over remote stretches of ocean – far away from the prospect of ground-based data collection.

But all that ended within the last few months, leaving scientists blind-sided and miffed by the shift in policy. The hope is that the policy decision will be revisited and overturned.

Critical importance

"The fireball data from military or surveillance assets have been of critical importance for assessing the impact hazard," said David Morrison, a Near Earth Object (NEO) scientist at NASA's Ames Research Center. He noted that his views are his own, not as a NASA spokesperson.

The size of the average largest atmospheric impact from small asteroids is a key piece of experimental data to anchor the low-energy end of the power-law distribution of impactors, from asteroids greater than 6 miles (10 kilometers) in diameter down to the meter scale, Morrison told SPACE.com.

"These fireball data together with astronomical observations of larger near-Earth asteroids define the nature of the impact hazard and allow rational planning to deal with this issue," Morrison said.


Morrison said that fireball data are today playing additional important roles.

As example, the fireball data together with infrasound allowed scientists to verify the approximate size and energy of the unique Carancas impact in the Altiplano -- on the Peru-Bolivia border -- on Sept. 15, 2007.

Fireball information also played an important part in the story of the small asteroid 2008 TC3, Morrison said. That was the first-ever case of the astronomical detection of a small asteroid before it hit last year. The fireball data were key for locating the impact point and the subsequent recovery of fragments from this impact.

Link in public understanding

Astronomers are closing in on a years-long effort to find most of the potentially devastating large asteroids in our neck of the cosmic woods, those that could cause widespread regional or global devastation. Now they plan to look for the smaller stuff.

So it is ironic that the availability of these fireball data should be curtailed just at the time the NEO program is moving toward surveying the small impactors that are most likely to be picked up in the fireball monitoring program, Morrision said.

"These data have been available to the scientific community for the past decade," he said. "It is unfortunate this information is shut off just when it is becoming more valuable to the community interested in characterizing near Earth asteroids and protecting our planet from asteroid impacts."

The newly issued policy edict by the U.S. military of reporting fireball observations from satellites also caught the attention of Clark Chapman, a planetary scientist and asteroid impact expert at Southwest Research Institute in Boulder, Colorado.

"I think that this information is very important to make public," Chapman told SPACE.com.

"More important than the scientific value, I think, is that these rare, bright fireballs provide a link in public understanding to the asteroid impact hazard posed by still larger and less frequent asteroids," Chapman explained. 

Those objects are witnessed by unsuspecting people in far-flung places, Chapman said, often generating incorrect and exaggerated reports.

"The grounding achieved by associating these reports by untrained observers with the satellite measurements is very useful for calibrating the observer reports and closing the loop with folks who think they have seen something mysterious and extraordinary," Chapman said.

Am I alone in thinking our government is one big anus?

I think they want to keep these rocks for themselves.

It's not the rocks, is it? It's that all that crap we put up there is coming back down, isn't it?

 :o

Maybe Rosin is telling the truth. WvB knew the progression. That's why he was a rocket scientist.

Sitting by my dish.  :-X :-X :-X
