Most probably a giant fireball exploding and creating this amazing flash in the sky!
This explosion disintegration occurred during the night between monday and tuesday.

"They hit, and then smaller ones hit in succession like, 'boom, boom, boom,'" Ryan said.
At first, Ryan thought maybe kids hiding in a treeline were pelting cars. But he noticed that the rocks appeared to have rained down from the clouds, as if they were meteors.
Laura Rinhart, a Loudoun County firefighter, said that the rocks likely were not from outer space and had instead come flying from a nearby rock quarry. Rinehart said that some rocks struck a home on Old Ox road and debris also hit the pavement near Oakgrove Rd.
A person who answered the phone at Loudoun Quarries on Thursday said he was not sure if the rocks came from their quarry, the only quarry in the area.
Some residents in the area heard a boom at around 10:30 a.m. that they thought sounded like thunder. Ryan said that stones then blasted car windows and damaged vehicles in a shopping center parking lot. He said he picked up some of the rocks and noticed that they had a burnt smell.
"One rock double the size of a softball was sitting on the sidewalk in front of a beauty salon," Ryan said. "If it had gone through there would have been lots of casualties."
Comment: In relation to the rock quarry, Old Ox Road is 3-5 miles West of the quarry, other locations reported are 2 miles or so East of the rock quarry. Why not rocks North, South, East and West? There isn't enough information to know for sure, but this seems fishy!
Comment: This story is a bit farfetched and reads like damage control. Here's another piece from USA Today with video of a rock coming from the sky. Would a controlled blast also create a burnt smell on the rocks?
The smell that is being given off by this meteorite is hard to describe. When I first smelt it, I tried to think of the proper words to describe the odor. I tried to think of things that had a similar smell:And...
"like hot metal, or like a cast-iron skillet that has over-heated, or like the metal filaments when you first turn on an electric heater.
Also, a lot like when you make sparks by striking two flint-rocks against each other.
Maybe a little like ozone, but with a more smoky, sulfurous aroma."
That's when the phrase "burnt gunpowder" came into my mind.

Chelyabinsk. Meteor SmellsIt's more likely space rocks coming into our atmosphere and the government owned media does not want the people to know they are about to be bombarded back to the Stone Age. What slimeballs.
A group of four observers of the Leonid meteor shower of 1833 reported a peculiar odour, "like sulphur or onions."
It was thought that "This apparent transmission of smells at the speed of light could be explained if they were due to nitrous oxide or ozone produced by an electric discharge." (Ozone [O3] a gas. From the Greek, ozein, for smell). Observers of the Texas fireball of 1 October 1917 also reported the odour of sulphur and burning powder as it passed.
A possible explanation is suggested by the following Chelyabinsk observer reports.
Field survey reports of smells were concentrated in the area surrounding the fireball trajectory. After an initial strong burst, the smells continued for a few hours. The eastern edge of this area coincides with the eastern edge of the glass damaged area. Arkhangel'skoe is the most western village where smells were reported. It is situated near the western edge of the glass damaged area. Fourteen villages reported similar smells, with nearly all described as a sulphur smell, a burning smell, or a smell similar to that of gunpowder.
These smells may have originated from the decomposition of Troilite (FeS), an iron sulphide mineral named after Domenico Troili, who first noted it in a meteorite that fell at Albareto, Modena, Italy in 1766. Troilite is one of the main components of the Chelyabinsk meteorite. Some burning smells may also have been caused locally when the shockwave dispersed soot from flues and stoves.
Respondents in Emanzhelinka, immediately under the fireball trajectory, also reported an ozone smell, similar to the smell after a thunderstorm. Ozone, with nitrogen oxides as by products, may have been produced in the immediate surroundings of the fireball by Ultra-Violet (UV-B λ= 290-320 nm wavelength) radiation from the meteor. This reinforces reports about sunburn caused by UV radiation from the fireball.

Omanawa resident and EOL CEO Terry Coles heard what sounded like two large explosions last Saturday night. He wondered at the time if they were sonic booms from a meteor.
His suspicions were confirmed on Tuesday when he set up a camera on the balcony to take continuous exposures for a timelapse video he's working on about the night sky over the Kaimais.
"I left the camera running as I needed several thousand consecutive images and went inside where it was warm," says Terry.
"Just after 11pm I heard three more explosions in quick succession, louder this time as if they were close by."
Suspecting he had missed something special he sifted through hundreds of images from Tuesday night and found something in just one frame.
"Two beautiful meteors one behind the other with an amazing green tail. The timestamp on the image coincided with when I had heard the booms."
"A stroke of luck that I had the camera pointing at the right bit of sky, even if it was only a wide angle lens so not a close up view unfortunately."
The colour is caused by the super-heating of magnesium atoms.

The meteor, which was first spotted when it was still 83 kilometres away from the planet, disintegrated 25.2 kilometres from the Earth's surface, and was snapped by the cameras of the AMOS project in the observatory of the Instituto de Astrofísica de Canarias Teide y Roque de los Muchachos.
The AMOS (All-Sky Meteor Orbit System) project has been up and running for only two months, and every night scans the sky in search of meteors using two detectors located 140 kilometres apart in Tenerife and La Palma. These devices can calculate the exact orbits and trajectories of the bodies they detect.
The technology was developed by the Astronomical and Geophysical Observatory of the Faculty of Mathematics, Physics and Informatics at the Comenius University in Slovakia, and won a gold medal at the INVENTO 2013 exhibition. Its intended use is for improving meteor and meteorite detection and prediction systems, and in future it is planned to install similar equipment in Chile in order to allow the southern skies to be monitored as well.

According to The Express;
The gigantic missile thought to measure almost a mile across will brush closer than previous monsters which have sparked a global panic.On this occasion a collision seems unlikely - but it doesn't take much of an orbital perturbation to put an Earth grazer onto a collision course.
Worried astronomers warned 1999 FN53, which is an eighth of the size of Mount Everest, will skim the Earth in THREE DAYS.
A collision would be nothing short of catastrophic triggering mass destruction, earthquakes and global extinction.
The monster is more than TEN TIMES bigger than other meteorites currently visible on NASA's Near Earth Object radar.
It is also double the size of the gargantuan 2014-YB35 which had astronomers around the world watching the skies in March.
Experts warn a collision would trigger an explosion similar to millions of megatons of TNT and would be capable of killing 1.5 billion people.
The boom was loud and clear, for a few seconds past mid-day following which people were alarmed and calls to one another began. The commotion led to creation of more confusion with some people saying it was a bomb blast outside the Secretariat, while others said it happened at the High School junction. There still were some more who said another blast had occurred at Lerie colony. The colony was the scene of a string of explosions earlier.
However, police officials confirmed that the sound was merely a sonic boom and not a bomb explosion, which was even heard in Wokha and Dimapur district.
It may be mentioned here that a sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound - in this case planes particularly jet fighters. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. The crack of a supersonic bullet passing overhead is a miniature example of a sonic boom.
Dora Marcouiller said she saw it while she was driving in Eatontown about 9:40 p.m.
"It flew southeast/northwest. It was as clear as day and crossed the top of the tree line. I saw the ball illuminating the sky with the tail of burning fire behind. It was huge and very distinct," the Eatontown resident said in an email to the Asbury Park Press.
Most meteors, or shooting stars, are visible as brief streaks of light. Marcouiller's description appears to match that of a "fireball," an unusually large and bright meteor. To be considered a fireball, a meteor must be at least as bright as Venus, according to an article from Geology.com.
Meteor-related websites reported sightings from Quebec, Canada to Maryland Friday night.
The meteor was bright light green in colour and split into two parts as it fell through the atmosphere, and could be seen for just a few seconds, around 1:58 a.m. Wednesday.
But unlike the loud daytime meteor heard nearly a year ago in Peterborough, there was no sound associated with Wednesday's fireball.
The fireball was also spotted at that time from Montreal, according to the American Meteor Society.
Meteor sightings were also reported to the American Meteor Society at 1:51 a.m. Wednesday from Niagara Falls, N.Y. and at 2:03 a.m. Wednesday from Ontario.
The Eta Aquariids is the current major meteor shower. It lasts until May 19 with a peak of May 6 and 7.
The April Rho Cygnids and the H Virginids showers were also active on Wednesday, according to the American Meteor Society.

The large meteor was spotted by several residents at around 10.10pm as it fell over the north west on what was a clear, crisp night.
Denise Kennedy-Scott was in her garden close to Blackburn Rugby Club when she spotted the fireball.
She said: "I was looking across the field and looked up to see what looked like a white shooting star to start with, but as it got closer — and it was moving slowly — it got bigger and bigger.
The fireball was associated with bright light and it seemed to move from the east to the west at a low altitude. The phenomenon lasted only for a few seconds. Unlike in the earlier instance, the fire ball was not accompanied by any sound.
Scientific observer Dr Rajagopal Kammath opined that this could have been a meteor and that there is no room for concern. He said that this is the time of the year when meteors called Lyrids drop to the surface of the earth. They travel from east to west and up to 20 have been cited in an hour at various places. He said that they would be more visible after midnight.
