NASA Stumped on Asteroid Belt Fireballs
Lee
Whenever I read an article where researchers or scientists are "puzzled," my eyes perk up. In the article below, the meteors are from the asteriod belt, but there's no mention of periodocity or the angle of orbit (elliptical orbits really perk up my eyes!). Perhaps someone can translate astronomer Ian Holliday's paper to get an answer:

The Fireballs of February
Feb. 22, 2012: In the middle of the night on February 13th, something disturbed the animal population of rural Portal, Georgia. Cows started mooing anxiously and local dogs howled at the sky. The cause of the commotion was a rock from space.
"At 1:43 AM Eastern, I witnessed an amazing fireball," reports Portal resident Henry Strickland. "It was very large and lit up half the sky as it fragmented. The event set dogs barking and upset cattle, which began to make excited sounds. I regret I didn't have a camera; it lasted nearly 6 seconds."
Strickland witnessed one of the unusual "Fireballs of February."

"This month, some big space rocks have been hitting Earth's atmosphere," says Bill Cooke of NASA's Meteoroid Environment Office. "There have been five or six notable fireballs that might have dropped meteorites around the United States."
It’s not the number of fireballs that has researchers puzzled. So far, fireball counts in February 2012 are about normal. Instead, it's the appearance and trajectory of the fireballs that sets them apart.
"These fireballs are particularly slow and penetrating," explains meteor expert Peter Brown, a physics professor at the University of Western Ontario. "They hit the top of the atmosphere moving slower than 15 km/s, decelerate rapidly, and make it to within 50 km of Earth’s surface."
The action began on the evening of February 1st when a fireball over central Texas wowed thousands of onlookers in the Dallas-Fort Worth area.
"It was brighter and long-lasting than anything I've seen before," reports eye-witness Daryn Morran. "The fireball took about 8 seconds to cross the sky. I could see the fireball start to slow down; then it exploded like a firecracker artillery shell into several pieces, flickered a few more times and then slowly burned out." Another observer in Coppell, Texas, reported a loud double boom as "the object broke into two major chunks with many smaller pieces."
The fireball was bright enough to be seen on NASA cameras located in New Mexico more than 500 miles away. "It was about as bright as the full Moon," says Cooke. Based on the NASA imagery and other observations, Cooke estimates that the object was 1 to 2 meters in diameter.
So far in February, NASA's All-Sky Fireball Network has photographed about a half a dozen bright meteors that belong to this oddball category. They range in size from basketballs to buses, and all share the same slow entry speed and deep atmospheric penetration. Cooke has analyzed their orbits and come to a surprising conclusion:
This camera is part of NASA's All-Sky Fireball Network. [more]
"They all hail from the asteroid belt—but not from a single location in the asteroid belt," he says. "There is no common source for these fireballs, which is puzzling."
This isn't the first time sky watchers have noticed odd fireballs in February. In fact, the "Fireballs of February" are a bit of a legend in meteor circles.
Brown explains: "Back in the 1960s and 70s, amateur astronomers noticed an increase in the number of bright, sound-producing deep-penetrating fireballs during the month of February. The numbers seemed significant, especially when you consider that there are few people outside at night in winter. Follow-up studies in the late 1980s suggested no big increase in the rate of February fireballs. Nevertheless, we've always wondered if something was going on."
Indeed, a 1990 study by astronomer Ian Holliday suggests that the 'February Fireballs' are real. He analyzed photographic records of about a thousand fireballs from the 1970s and 80s and found evidence for a fireball stream intersecting Earth's orbit in February. He also found signs of fireball streams in late summer and fall. The results are controversial, however. Even Halliday recognized some big statistical uncertainties in his results.
NASA's growing All-Sky Fireball Network could end up solving the mystery. Cooke and colleagues are adding cameras all the time, spreading the network's coverage across North America for a dense, uninterrupted sampling of the night sky.
"The beauty of our smart multi-camera system," notes Cooke, "is that it measures orbits almost instantly. We know right away when a fireball flurry is underway—and we can tell where the meteoroids came from." This kind of instant data is almost unprecedented in meteor science, and promises new insights into the origin of February’s fireballs.
Meanwhile, the month isn't over yet. "If the cows and dogs start raising a ruckus tonight," advises Cooke, "go out and take a look."

Actually thinking about it seeing where the u.s is facing at 2am on February will show a star map (rough) direction to give an idea of where there coming from, unless there coming in retro grade witch would explain them being slowed down!

I wish I could say that I know the coordinates or orbits. Perhaps Ian Holliday's paper explains it, but it's too deep for my layman's mind to grasp. Nevertheless, something over the past several years seems to be affecting the Sun and in turn, the other planets in our Solar System. I can'y say I've EVER heard of a fireball period from NASA. Meteor showers, yes, but fireball showers, no. It's an interesting clue, I suspect! What made me seek info on fireballs was that on 21 Feb at 6:34pm EST, I saw two green flashes in the Northern sky and searched the net to see if there was anything on fireballs. I came up with the NASA article...
Nibiru collision debris? Who knows??

Hi, Amy--
I think it's out at least 50 AU from us at present. But that doesn't mean that changes can't be felt here as it continues inbound...
We're approaching the end of a 26,000 year cyccle and anything's possible.

You just might be close to the answer my friend :) .......One of the Infrared images from the South Pole Telescope of the Dwarf Star that is out beyond of Pluto.And here is a computer generated image showing the projected path of the outermost planet of the mini-dwarf system. It is beleived to be Nibiru, and it is projected to pass through our system somewhere between Mars-Jupiter-Saturn in Dec of 2012Sincerely,

Hhhmm interesting! Have you found any co-ordinates at all for these slow-mo comets? If there coming from the galactic plain then it could be another hint of sol accelerating, if not recently I been thinking there is also something else that could be moving sol and affecting the solar system this with the same anomalies as what we are seeing (sols binary companion), if indeed there is a darkstar out there, and it has past aphelion then obviously the 2 bodies will now be swinging back towards each other at an accelerated rate.

Wouldn't that be a little difficult to hide from backyard astronomers like myself? I look there all the time, but just see Mars and Jupiter...
How are your friends tracking it, and can you share any data with the group?

Lee ... greetings :)The last info I have received is that Nibiru is somewhere out in the region of Jupiter-Mars ... about 8 AU's. Friends of mine have been tracking signals from that region of space.computer enhanced Microwave image showing 6 of 7 planets.

This stuff has been bouncing round the internet since 2008 give or take a year...there is a disinformation program out there about nibiru and I believe from my research into it that this image real or not is part of that program, firstly to make you believe 2012 is the coming date and when 2013 comes around and we are all still here and no nibiru then in your own minds you will disbelieve in nibiru. The power of suggestion is a great force in controlling the masses and the governments know this, the less that see the truth will follow the dictation of powers at hand and that my friends is common sense and the truth of it! Don't loose your disbelief in such issues and look for factual data like people on this site do provide!
See it from my point of view, on this site I question there points of view here, they question mine, I offer a different opinion we agree and we disagree, our differences are our bond and that benefits all who read this site cus it shows humanity and honesty!
This leaked S.P.T footage is utter crap, its so perfectly focused on bending your minds its un really well planned in my opinion. Lee is very right when he says to a backyard astronomer it would be hard to hide, if it was in the area stated it would be visible now to the naked eye and seriously you wouldn't need a telescope to see it!

Hi, Amy--
Jupiter is only 5.6 AU and Mars is 1.5 AU...if it was in fact at 8 AU, it wouldn't be near these planets, it would be closer to Saturn. But, I don't see it there, either.

Hi, Amy--
If the Dark Star is inbound, it would have certainly an effect on our heliosphere, which is about 84 AU out from the Sun. In fact, it seems that the heliosphere is going through changes, as Andy points out in this article: http://www.darkstar1.co.uk/heliopause.html
However, if it was as close as your friends say, the heliosphere would have been much more distorted, way much more distorted. So, I tend to go with Andy's theory which brings the Dark Star back at a much later date, like 3751 or so...

Thats the best answer I have ... somewhere in the region near Jupiter ... that was all I was told
