Kachin State and Sagaing Region

Over 14,000 people have been displaced by flooding from the Irrawaddy river in Myanmar's northern state of Kachin.

According to reports, the worst hit area is Myitkyina, where 2,000 households have been forced to leave their homes. Over 20 relief camps have been set up to accommodate those displaced.


Question

Loud boom reported in South Texas remains a mystery

Neighbors from La Vernia to Karnes City reported hearing a loud boom Wednesday afternoon on social media.

While many people are speculating as to what it may have been, right now the loud boom continues to remain a mystery.

Wilson County authorities said they began getting calls into dispatch reporting the boom around 1:30 p.m. Wednesday. Sisters Bailey and Molly Runty were at home in their home in Adkins when they heard it.

"We were just sitting in the room, and then we just heard it and then I started freaking out," Bailey said.

The girls described the boom as being so huge that it shook their house.


Comment: Dr. David Wood, an astronomy professor with San Antonio College, reported to Wilson County News that the mysterious 'sonic' boom likely came from a exploding meteor:
"Given how wide-ranging this sound was, a bolide is the most likely culprit," Wood told the Wilson County News.

Bolides are large meteors that explode in the earth's atmosphere.

At night, these appear as fireballs in the sky, Wood explained, but at midday, "it would be much less noticeable."

In February 2013, a large bolide entered earth's atmosphere over Russia as a very visible fireball. "The percussive effect broke windows and caused injuries to people on the ground," Wood said.

What Texans experienced last Wednesday could have been a bolide, according to Wood, although he couldn't say definitively.

"We do get hit all the time [by these]," he said. "They're usually much smaller."

There's "a lot of junk in earth's orbit," the professor said, adding that 1,747 fireball sightings were recorded in the last 30 days.

Meteors, he explained, can enter earth's atmosphere at about 50,000 mph. If it was small, say a few meters in diameter, and exploded very high — 80 to 100 kilometers, or about 60 miles — above the earth, a bolide might have avoided detection.

"All the evidence seems to really point that direction," Wood said.

Very rare meteor cluster recorded in Maranhão, Brazil

A very rare cluster of meteors was registered in the early hours of June 26 from the BRAMON EMM2/MA Station managed by Edgar Merizio in São José do Ribamar, Maranhão, Brazil. Where at least 9 meteors registered simultaneously in less than 1 second, all parallel to each other.

Meteor cluster like these originate from the same meteoroid that broke apart before it hit Earth. Usually this fragmentation occurs a few hours, perhaps days, before its encounter with the terrestrial atmosphere.

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.

Large meteor fireball caught on camera streaking over South Florida - UPDATE: Space debris reentry

fireball
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 this was not a meteor fireball but rather a space debris reentry - possibly CZ-3B R/B 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)

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:

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.
