The GOES-16 satellite is designed to detect flash lightning. He saw the asteroid on Saturday.
On Saturday afternoon at 4:25 pm meteorologists noticed an unusually bright flash over the Caribbean Sea 170 miles south of Puerto Rico.
His light was visible in a large area like Rhode Island – too big to be a stroke. There were no clouds in that area as well.
We'll tell you what's true. You can shape your own view.

It had to be something else. The answer turned out to be somewhat out of this world.
In the radar of San Juan, splashing of debris appeared. This is an indicator of the meteor or the influence of the asteroid.
How big was it? A diameter of 13 to 16 feet or the size of a car.
As the asteroid entered the atmosphere, Spaceweather.com reports that the Infrasound Station of the Organization for the Prohibition of Nuclear Test at Bermuda discovered "explosion-related" airborne waves.
The recording station is more than 1000 miles away from the asteroid attack, and the station has "heard" it.
But ordinary sound can not travel so far; if he could, then everyone in Miami, Cuba and Puerto Rico should hear the explosion. It was a different type of sound: infrared.
People can detect sounds between 20 and 20,000 Hertz. It's a measure how many times in a while the air pockets are vibrating back and forth, shaking the sensory receptors in our ear that process sound.
Dogs can hear twice as large frequencies – close to 40,000 Hertz – which is why they will cling over the dog gun that we just can not hear.
When you reach the low side of the spectrum, speak "infrared". The infrared wave can only have a few vibrations per second, which is why its frequency is too low to be heard. But that does not mean that the sound is not there.
The asteroid explosion produced a dramatic infrared signal in the form of an "air wave" that appeared around it.
According to the immortal images of evaporation shared by SpaceWeather.com, the asteroid is divided into at least three pieces. The explosion released energy of over 6,000 tons of TNT, and the fireball itself weighed 200 tons.
Since infrared waves have a very long wavelength, they can travel long distances.
Combining knowledge of where the asteroid hit the Bermuda signal size, Peter Brown's meteorologist expert from the University of West Ontario managed to conclude that it was a "multi-meter asteroid close to Earth."
The Hawthorne University Institute of Astronomy wrote that the asteroid was small enough to burn and enter the Earth's atmosphere (SpaceWeather.com wrote small asteroid fragments, known as meteoroids, likely to scatter the ocean surface).
But objects in the universe somewhat may pose a threat to the people of the country, a meteorite witness in February 2013, which injured more than 1,000 people in Chelyabinsk in Russia.
NASA has identified most of the major Earth's facilities, one that could lead to a global disaster if it happened (it is expected to happen once every 700,000 years). However, detection of smaller objects, which may be detrimental, has proved more challenging.
Namely, the Hawaii University Institute of Astronomy has revealed that it has discovered a relatively small asteroid on Saturday in a press release.
His telescopes watched the asteroid "four times in the range of 30 minutes," the statement said. That was about seven o'clock before the asteroid struck.
At that time, the asteroid was alone [310,000 miles] with Earth – or 1.3 times distance from the Moon. "
When they coincide with data from another telescope at a distance of 100 miles, "predicting the asteroid input path significantly improved" and it was believed that the "asteroid" would probably hit the ground.
Estimated objects of the size of the Sabbath asteroid can be discovered about half a day in advance, with larger – such as the 2005 Chelyabins event – a few days out. That was the size of a "small house".
"For the first time astronomers from the University of Hawaii have shown that their ATLAS and Pan-STARRS telescopes can provide enough warning to keep people away from the point of the incoming asteroid," the institute wrote.
