A meteoroid burned up in the atmosphere early Thursday, producing a fireball that was seen by people across San Diego County, according to the American Meteor Society.

"More than 110 witnesses have reported a large blue-green fireball over Southern California on Februray 11th around 6:35am PT (14:35 UT)," the AMS says online. "The fireball was seen primarily from California but witnesses from Arizona also reported seeing the fireball."

The eyewitnesses include Francis French, education director at the San Diego Air & Space Museum. He saw the meteor while he was driving to work on state Road 94.

"The front of the light looked like the arc of a welder's torch; it was blue and incredibly bright," said Francis French, education director at the San Diego Air & Space Museum in Balboa Park. "And it had a yellowish tail that was very textured."

Another eyewitness, Harold McManus, said, "I was accessing Sunset Cliffs via Pt. Loma Nazarine University campus. I was on the bluffs about to climb down to the beach when I saw it. It came in from the north almost horizontal. It had a slight downward accent as it headed to the south. I was looking west over the ocean.

" It was spectacular. Bright green like a welders arc with a long tail and relatively slow moving. It fragmented into several pieces as it died. They looked like little sparks. I looked at my watch as I was going to report it to the AMS. It was 6:37. The sky was starting to get light."

NASA unsure how close enormous asteroid 2013 TX68 will come to Earth on March 5th

A sizable asteroid is set to rocket past Earth next month, and scientists, while confident it will not strike our planet, are nonetheless unsure how close it will actually come.

Discovered two years ago, near-Earth object 2013 TX68 is roughly the size of a basketball court; fairly small, as asteroids go. TX68 is locked in an orbit that brings it near our planet every few years.

The next transit is expected to occur March 5. How close will it come to Earth? Scientists aren't exactly sure.

"The variation in possible closest-approach distances is due to the wide range of possible trajectories for this object, since it was tracked for only a short time after discovery," NASA officials said in a statement released Wednesday.

While there's no risk of impact, the asteroid could come as close as 11,000 miles from Earth, or inside the orbit of many satellites. For comparison, the Moon is 238,900 miles from Earth.

On the other extreme end of the scale, TX68's transit could occur 9 million miles away.

Meteor caught on camera over Saudi skies

A glowing object believed to be a large meteor was captured on camera as it crossed Saudi skies at night, a local newspaper reported on Wednesday. An eight-second YouTube film published by Sabq Arabic language daily showed the object lightened up the sky in the Northern Rafha town as it moved fast from East to North before disappearing.

The paper said many residents captured the object with their mobile phones and quoted well-known Saudi astronomer Khaled Al Zuaq as saying he believes it was a meteor.

"The object appeared to be a large meteor which was seen crossing the Saudi skies at around 10.30 pm," he said.

Mini ice age could be unleashed by a medium-sized asteroid strike

A strike by a medium-size asteroid could change Earth's climate dramatically for a few years, making life difficult for people around the world, a new study suggests.

Such an impact on land (as opposed to at sea) could cause average global temperatures to plunge to ice age levels and lead to steep drops in precipitation and plant productivity, among other effects, researchers said.

"These would not be pleasant times," Charles Bardeen, of the National Center for Atmospheric Research in Boulder, Colorado, said in December during a presentation at the annual fall meeting of the American Geophysical Union (AGU) in San Francisco.

Saturday night, hundreds of Danes reported the sky suddenly lit up and a loud bang followed shortly after

On Saturday night, hundreds of Danes witnessed a spectacular phenomenon as the sky suddenly lit up and a loud bang from an explosion echoed across northeastern Zealand, reports DR.

According to Johan Fynbo, a professor of astronomy at the Niels Bohr Institute, everything indicates a meteorite hit Denmark at about 10 pm.

"It must have been a relatively large meteorite. Not the size of a car, but perhaps the size of a handball," Fynbo told DR.

As a meteorite passes through the Earth's atmosphere, it burns and creates a visible flash of light in the sky. The bigger the meteorite, the stronger the light, explained Fynbo.

One person was killed and three others were injured when an object believed to a meteorite fell on the campus of a private engineering college near Natrampalli in Vellore district in northern Tamil Nadu early on Saturday.

According to police sources, a loud blast was heard near a water tank shortly after midnight on the Bharathidasan Engineering College premises in K.Bandarappalli village. Kamaraj, a college employee, who had gone to drink water suffered serious injuries and was declared dead when taken to the Vaniyambadi Government Hospital. Three others suffered minor injuries. Window panes and wind screens of buses parked nearby and the water tank were broken in the impact of the blast. A crater was formed at the site of blast.

Though there was suspicion that it was a bomb blast, preliminary investigation by forensic and bomb experts showed no sign of any explosive substance at the scene. Pieces of a rare kind of stone were found and samples taken for analysis by scientists.

Multiple sources have reported seeing some sort of fireball or meteor over the skies of southern Wisconsin Monday evening.

The Muscoda Police Department caught video of the fireball on a squad dash cam facing east:


That wasn't the only sighting. UW-Madison's Atmospheric and Oceanic Sciences school also caught the spectacular display from one of their rooftop cameras.

Comment: The American Meteor Society (AMS) received 160 reports yesterday about a fireball seen over Wisconsin and neighbouring states. On January 30th 2016 there were 880 reports of meteor fireball sightings over Northeast US and Canada. See also: Fireball seen over Northeast US
