Last night in Australia, near-Earth asteroid 2010 WC9 glided silently across the starry sky of Brisbane while the city's residents slept. Well... not every resident slept. Amateur astronomer

Dennis Simmons was wide awake and recorded the flyby:

"The asteroid moved rapidly through the constellation Hercules shining about as brightly as a 15th magnitude star," says Simmons. "The 'wobbly' appearance of the trail is as a result of slight periodic errors in the telescope mount's gear train. This is not caused by the asteroid tumbling!"

Tonight, the view will improve - a lot. On May 15th, 2010 WC9 will fly through the Earth-Moon system, splitting the distance between our planet and the Moon. At closest approach (203,000 km), the asteroid will glow like an 11th magnitude star (~40 times brighter than shown above) as it races through the southern constellation Pavo (the Peacock).

2010 WC9 is known as the " lost asteroid" because astronomers lost track of it soon after it was discovered in November 2010. The asteroid receded from Earth and didn't return for nearly 8 years... until now.

Estimates of 2010 WC9's size range from 60 m to 130 m wide. This puts it in the class of the Tunguska impactor, which leveled a forest in Siberia in 1908. And it is at least 3 times as large as the Chelyabinsk meteoroid, which exploded in the morning sky over Russia on Feb. 15, 2013, shattering windows and knocking people to the ground.

There's no danger of a collision this time, though. Analysts are certain 2010 WC9 will not hit Earth - neither this week nor in the foreseeable future. New observations of the asteroid in recent days have extended our knowledge of its orbit and eliminated it as a threat for at least the next 100 years.

2010 WC9 is invisible to the naked eye. Advanced amateur astronomers can photograph it, however, using mid-sized telescopes equipped with low-light video cameras. Southern hemisphere observers are favored, especially those in South Africa and southern parts of South America where the asteroid will be high in the night sky at closest approach.

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.

For upwards of two months social media sites such as Facebook and NextDoor have been buzzing with people reporting and trying to identify the source of a loud boom.

Some have turned to the Hamilton County Sheriff's office for answers. As a result, Sheriff's deputies have investigated.

"Each investigation has been unfounded," Lt. Matt Guy said. "There are no reports and there is no ongoing investigation, as there have been zero reports of property damage or persons injured."

The Hamilton County Communications Center has received calls reporting a loud boom. The majority of the callers were from the Salem Road area near the Anderson Township, Mount Washington boundary.

On April 21 multiple callers reported a loud boom, according to communications center records. One told the dispatcher that they also saw a flash of light and heard voices.

Nearly a month after these reports, the source of the noise remains a mystery.

Frustration is growing as residents look for answers and the booms continue.

On May 13, Anderson Township resident Steve Hart posted a video from his home security cameras to his YouTube channel. The footage is of a flash of light and loud noise.

"For weeks concerned residents have heard and seen explosions that are not from fireworks, sonic booms, or other sources. Last night, I captured one such blast on my security cams and I am asking the Hamilton County Sheriff's Office to start taking this as seriously as we do," he wrote in the video's description.

Anderson Township Administrator Vicky Earhart has been actively engaged in efforts to identify the noise.

According to a summary she shared with staff, Earhart researched underground mining, fracking, and earthquakes as possible noise sources. There were similar reports of noise in 2014 that were linked to a mine in another state, she wrote. She found no evidence of booms in neighboring areas that coincided with the timing of booms heard in the area of the Mount Washington/Anderson Township border, according to the summary.

Another factor in her research was the flash of light some residents reported in late April.

"While we have no idea what is causing the noise, it appears as though both times the loud booms were heard on a Saturday evening approximately one month apart," she wrote. "Similar sounds that were heard in Colerain in January turned out to be residents shooting off mortar-type fireworks."

Earhart was on vacation and unavailable for comment for this article. Her summary noted that no injuries have been reported as a result of the noise

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."

Before readers remind us that we're surrounded by military bases, those in the vicinity of the reports say Tuesday night was business as usual. Fort A.P. Hill has issued an aviation noise alert through Friday for low-flying aircraft training, but nothing from the Army post was in the air at the time in question, said Michael Meisberger, public affairs specialist.

He said the next statement in hushed tones.

"From what I understand, it may have been a meteor," he said. "I can't tell you if it's real or if it was somebody's imagination, [but] that's what I heard."

Operators in the 911 center in King George County felt the earth move and got lots of calls from residents who said the same, said Sheriff Steve Dempsey. There were no reports of explosions, fires or other disasters that might cause that kind of noise.

"Everybody felt it, but had no idea where it came from," Dempsey said.

Facebook posts were filled with descriptions and possible answers, ranging from alien invasions to thunderclaps.

Alyssa Anne Halderman posted that she "heard a loud boom here in Caroline Pines [in Caroline County] and the house shook."

Dan Dunmire heard it in Fredericksburg, and the noise scared Mandie Hartford in King George, who immediately checked the baby monitor to see if the noise had awakened her twins.

Michele Spears thought she had imagined it.

"I felt whatever it was and there seemed to be a faint rumble," the King George woman posted on the King George - Westmoreland General Forum page. "My dog and I just stared at each other, waiting for more, but nothing happened, so I chalked it up to thunder and went to sleep."

Mike Hankey, operations manager for the American Meteor Society, said he received 10 reports from residents in North Carolina and Virginia about the fireball. Two reported sounds with their sighting, and two saw meteor fragments.

"Occasionally large fireball meteors can produce sonic booms and rumbling sounds," Hankey wrote in an email. "Often times this means the object penetrated deep enough into the atmosphere to survive and possibly leave meteorites, but not always."

Several thousand meteors of fireball magnitude burst through the Earth's atmosphere every day, according to the Meteor Society website, but simply aren't seen.

Most take place over oceans or uninhabited regions, and many are masked by daylight. Those that happen at night have smaller chances of being seen because there aren't people out looking for them.

"They're not uncommon," said David Abbou, a Stafford County resident and member of the Rappahannock Astronomy Club who writes an astronomy column for the newspaper.

In 1992, he was living in Dale City when he saw a bright light flashing from the window. It was a clear night, so he knew it wasn't lightning.

News reports confirmed his assumption that it was a fireball meteor. Because it was a pleasant Friday evening, lots of people were out and saw it, he said.

"The coolest part was it landed on an unoccupied car in Peekskill, N.Y.," he said.

The car's owner might have had a different opinion on that meteor matter.

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?

- R Dub (@r_dub_1)May 16, 2018

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

Marine Corps officials said that if a sonic boom did occur over Carmel Valley this afternoon, it wasn't them. U.S. Navy officials have not yet responded.

This meteor event was recorded over the Mediterranean Sea on 23 May 2018 at 1:37 local time (23:37 universal time on 22 May).

The event was produced by a fragment from an asteroid that hit the atmosphere at about 90000 km/h. The fireball began at an altitude of around 89 km over the sea, and ended at a height of about 19 km.

The analysis of its atmospheric path shows that this was a meteorite-producing event. The meteorite would have fallen into the sea.

The event was recorded by the meteor observing stations operated by the SMART Project (University of Huelva) from the astronomical observatories of Calar Alto, La Sagra, La Hita and Sevilla.
