Social media is buzzing with reports of a meteor spotted over the South Coast on Friday night.

On the Facebook group Australian Meteor Reports, administrator David Finlay said the meteor was spotted about 9pm on July 5 and believed it had come to ground somewhere in Victoria.

"I have reports of sonics from Forest Hill (Melbourne) to Mallacoota Vic. That's a distance of 400km. I've never heard of sonics being reported so far apart," he said in a Facebook post to the group.

He said sightings had been reported from as far north as Sydney and Orange.

"From these reports, and as long as this object was over land and not the ocean, I'm already predicting there are now meteorites on the ground somewhere in Victoria from this fall," he said.

Meteor or 'space junk'? Something broke apart in the sky over South Florida

Was it a meteor, a comet, space junk falling to Earth or something else?

Whatever it was, residents across Florida took to social media to show photos and video of a large fireball streaking across the sky early Wednesday morning.

From Deerfield Beach to Vero Beach, Scripps Station WPTV in West Palm Beach received calls and emails from people who were perplexed by the strange object.

Grace Theodore said she was walking out of a Walmart in Deerfield Beach around 2:19 a.m. when she recorded video of what she called a "double meteor."

Comment: According to the American Meteor Society (which cites the US Air Force), this was not a meteor fireball but rather space debris reentry - possibly CZ-3B R/B, a Chinese satellite launched in 2015.

Meteor streaking over Brisbane on June 22nd.
Residents in northern NSW were a little shaken up on Sunday evening when a series of loud bangs was heard coming from the sky.

"It sounded like a bomb dropping actually but there was a zooming sound and small sonic boom, I thought it was made by a fast military jet," one person wrote on Facebook on the strange noises around 5pm.

"Heard it in Lismore and it shook the house! Pretty awesome sound," another person added. One person even wrote that they saw an "amazing glow over the roof line" as well as the strange noise. "Heard it Nimbin shook my walls," another Facebook user chimed in. 'The windows shook'

Dave Reneke from Australasian Sky and Space Magazine, confirmed to ABC that the mysterious noise was most likely a meteor burning and breaking up as it headed toward earth. "It sounded like a big fire cracker going off, but the windows shook," he said.

Huge late-night explosion that has left Kilmarnock, UK residents mystified (Update)

Moments before the loud explosion

Kilmarnock residents were woken by a huge explosion in the early hours of this morning.

The mysterious event saw some people from the John Walker estate, just off Western Road, in the town woken from their slumber because the bang was so loud.

Video footage captured by a resident's CCTV shows the night sky lighting up just after 1am.

Many reported hearing a loud bang followed by a bright light.

Some theories suggest that the explosion could have been a power generator or an electrical transformer.

Comment: The Daily Record reports the explosion and flash of light came from a high voltage underground cable fault:
A Scottish Power spokeswoman told the Standard that the incident was the result of a "high voltage underground cable fault."

The spokeswoman added: "Power was restored to properties in less than an hour.

"We apologise for any inconvenience caused."


Astronomers spotted a car-size asteroid just hours before it exploded over Puerto Rico

Astronomers discovered a car-size asteroid hours before it slammed into Earth and burned up in the atmosphere this past weekend, news sources report.

Scientists in Hawaii initially spotted the asteroid, named 2019 MO, on Saturday (June 22). Soon after, the heavenly traveller broke apart in large fireball as it hit the atmosphere about 240 miles (380 kilometers) south of San Juan, Puerto Rico, according to the University of Hawaii.

This is only the fourth time in history that scientists have spotted an asteroid so close to impact. The other three detections all occurred within the past 11 years, including 2008 TC3, 2014 AA and 2018 LA, which landed as a meteorite in southern Africa just 7 hours after it was noticed by scientists.

Unlike 2018 LA, Earth's latest visitor was harmless and didn't make it to the ground. But the asteroid, 13 feet (4 meters) long, still made a spectacular fireball that was equivalent to about 6,000 tons of exploding TNT, according to the Center for Near Earth Object Studies (CNEOS), which is run by the Jet Propulsion Lab in Pasadena, California.

The asteroid's impact was so powerful, even satellites in orbit spotted it. Satellites operated by the National Oceanic and Atmospheric Administration (NOAA) recorded its impact and destruction at 5:25 p.m. EDT (21:25 UTC), as you can see on this tweet below.

Comment: As Fireball Numbers Increase it is well worth remembering what can come out of the sky, without any warning at all:


Mysterious 'loud boom' heard over small English town spooks residents

The bang was powerful enough to trigger car alarms and left houses and office blocks shaking, and instantly sparked a debate online over its cause.

Derbyshire Police have revealed that the loud explosion heard in Derby city and the surrounding countryside area on Thursday morning was a sonic boom caused by a Royal Air Force (RAF) jet.

According to the authorities, the RAF Typhoon jet triggered the "loud bang" while moving at high speed to intercept an Air India flight from Mumbai to Newark after receiving a "security alert."

Comment: The BBC posted footage of the 'sonic boom':
Claire Murray said she was filming her dog in her garden in Breaston, near Long Eaton, between 09:45 and 10:00 when she heard the noise.


What was that loud boom near Clemmons, North Carolina? No one knows

Numerous people reported on social media that they heard a loud ground-shaking boom around 9 p.m. Monday night in Clemmons and western Forsyth County.

However, state and federal officials say they don't know why it happened or what it was.

Scott Sharp, a meteorologist with the National Weather Service in Raleigh, said the boom could have been distant thunder coming from storms that moved through Davie, Yadkin, Stokes and Davidson counties at the time.

Dan Blakeman, a geophysicist with the National Earthquake Information Center in Denver, said there were no reports of earthquakes anywhere Monday night in North Carolina.

The mystery boom in the wee hours Saturday was a literally moving experience for Bryan Adlam.

"I heard the boom - it was quite loud - but I also felt it. I felt my house move," said the real estate agent, who lives in the Crown Point neighbourhood near the escarpment.

Turns out bewildered residents across the city heard the same thing after 2 a.m. On the beach strip. The Mountain. Even Ancaster.

Adlam posted a question about the sound blast on Facebook that quickly spawned 500-plus comments, theories and, obviously, fart jokes.

But so far, the source of the thunderous bang remains a mystery.

Was it a supersonic jet? An industrial accident? A skyquake? Nobody seems to know.

People living in the New Tripoli area of Lehigh County want to know what caused an explosion Tuesday morning.

They say they heard or felt a blast, but authorities say they can't determine a cause.

Micki Tapper says she was awake at 7:30 a.m. That's when she heard it.

"There was just a really loud boom. My house shook, my windows shook," Tapper said.

The sound is picked up by her security camera microphone. You can hear a noise, but you can't discern much about it, or how far away it was.

Still, it was alarming. Tapper says she went outside to look around her home because she thought a tree fell on her house.

Comment: You can hear the booming sound starting at :25 in WTMZ's video coverage.

Nuke sensors detect asteroid explosion in the atmosphere over the Caribbean

On June 22nd at 21:25 UT, a small asteroid entered Earth's atmosphere and exploded in broad daylight south of Puerto Rico. Airwaves recorded by the Comprehensive Nuclear Test Ban Treaty Organization's infrasound station in Bermuda pegged the blast energy between 3 and 5 kilotons of TNT-a fraction of a WW II atomic bomb. The explosion was clearly visible in images from NOAA's GOES-16 weather satellite:

Meteor expert Peter Brown of the University of Western Ontario says the infrasound signal is consistent with a "small multi-meter sized near-Earth asteroid." According to data compiled by NASA's Center for Near Earth Object Studies, asteroids of this size and energy hit Earth's atmosphere about once a year. That means it's rare-but not exceptionally so.
