A loud boom was heard around San Diego Wednesday afternoon.

A Carmel Valley resident sent a tweet at 12:26 p.m. asking if the noise was a sonic boom. Another person said their house rattled around the same time.
Felt it over here in Carmel Valley, too quick for an earthquake? Sonic boom?

FOX 5 reached out to local military bases to find out if they were involved in making the noise.

Meteor fireball seen in skies above Fredericksburg, Virginia


Witnesses described seeing a fireball, similar to this stock photo, on May 15.
Fredericksburg-area residents reported that an object from outer space tore through the sky Tuesday, just before midnight, leaving in its wake a sonic boom heard by residents from Culpeper to Colonial Beach.

The meteor was "the brightest and most amazing fireball I've ever seen, in person or in any videos," wrote Chase K. of Dahlgren in his report to the American Meteor Society. The night sky appeared like a giant lightning strike and it was almost as bright as daylight when the primarily red and orange fireball was seen, he said.

He didn't notice any sound, but an observer who identified himself as William G. of Colonial Beach wrote in his report to the society that there was a loud boom and "ground shake similar to a military artillery round."

Don't even try telling Anderson Township resident Kimberly Kempke that the "boom" noise people are hearing around her community is nothing more than fireworks.

Anyone suggesting this obviously hasn't really heard the noise being referenced by people on her two Facebook groups - Watchful Eyes in Anderson and Watchful Eyes of Mt. Washington, she said.

The sounds are "true booms. They sound like a powerful explosion," Kempke said.

"It's unlike anything I've ever seen or felt before. And I've been very up close with the WEBN Fireworks many times," she added.

A fireball was captured in the Tucson AZ sky at 12:50 am using two cameras, a Nikon D810 with a 8 mm fisheye with 15 second long exposures and a Starlight Xpress Oculus all sky meteor camera with 30 second long exposures. The fireball left a smoke trail that persisted for a few minutes also shown.


Rogue star Gilese 710 hurtling towards our solar system will arrive sooner than we thought

Gliese 623 A

Gliese 710 may be as dim as a red dwarf star, like Gliese 623 A (M2.5V) and B (M5.8Ve) at lower right.
According to new calculations, we may have a little less time to prepare for a star on course to kiss the edges of our Solar System.

Yep. Dwarf star Gliese 710, which we've known about for some time, could now arrive in 1.29 million years, instead of the previously calculated 1.36 million years.

Gliese 710 is what is classified as a rogue star - one that has gone roaming across the galaxy, free of the gravitational chains that normally hold stars in position.

At a speed of 51,499 kilometres per hour (32,000 miles per hour), it's not quite fast enough to be considered a runaway star, but it's still travelling at a hefty clip.

Comment: Whilst the flyby is apparently over a million years away, we should bear in mind that Gilese 710 is a body we know about and the predictions are based on our current models, because it is often the case that we are taken by surprise:

Some people in Southeast Michigan have reported hearing a loud "boom" that they say sounded, and felt, like an explosion.

People living in and near Bedford Township tell 13abc they heard the loud noise just before 8:30 Sunday evening.

Some viewers say they believe it happened on Erie Road between Crabb and Minx.

A 13abc crew drove to the area and found a Monroe County Deputy patrolling the road.

That deputy told 13abc he was called to check out the sound, but hadn't found anything suspicious.

The law enforcement officer did say, however, that he felt his cruiser shake around the same time that noise was reported.

Meteor fireball lights up the sky over New Jersey

A bright meteor described as "bright and beautiful" streaked across the sky over New Jersey on Thursday.

"I was driving Route 206 North just south of the Somerville Circle just before 9 p.m., and I saw something streak across the sky, with a pretty bright ball with a long tail. Then it just went dark," Lorna Morehead of Bridgewater told New Jersey 101.5.

Reports to the meteor reporting website amsmeteors.org came from New Jersey and neighboring Pennsylvania, Delaware, and New York. In New Jersey, reports came from Keyport, Greenwich, Scotch Plains, Montclair, Lebanon, Manasquan, Rockaway, Franklin Lakes, and Springfield Township in Union County.
