Have you spotted the meteor over Florida? (Not in the photo – it's a fireball seen from Australia in 2011.)

It seems like a meteor has just exploded on the continental United States. According to footage filmed on social media, it appears to have been destroyed over Florida on March 30 at 11:52 pm Eastern Time. Shortly after its appearance, the existence of the meteor was confirmed by a scientific agency, but perhaps not the one you expected: the National Weather Service. So how did they manage to see him?

About 60 tons of space dust from meteors, comets, etc., fall on the Earth. every daybut as it is so good, it must be incredibly fortuitous and incredibly cautious to notice it. Meteors of all shapes and sizes also enter our atmosphere, but thanks to the fabulous friction and the compressed air that accumulates in front of them, most of them do not reach the surface and become meteorites in good faith. Their ignition, however, means that unlike all these interplanetary films, we can spot meteors if they fall in the right place.

As last December Meteor of the Bering Sea& nbsp; nevertheless demonstrated, even important meteors can go unnoticed when they burn away from the eyes of someone. This particular space rock, which emitted 173 kilotonnes of TNT energy when it exploded for 26 kilometers over isolated rivers, was only seen thanks to a variety of mechanical sensors and satellites, which detected low frequency. boom and the smoke process she left behind.

Speaking of which, there are many more satellites above our heads than we wish to imagine. One, the operational geostationary environmental satellite 16, or GOES 16, launched in November 2016; The rotation rate of the planet, which corresponds to 75.2 ° W, makes it possible to constantly monitor the weather that it does in the Americas.

As part of & nbsp; this & nbsp; mission, it is equipped with Mapping geostationary lightning, or GLM, which allows it to capture bursts of energy in the infrared part of the electromagnetic spectrum. & nbsp; Although it means he is able to & nbsp; detect lightningwhether they happen day or night, it also helps to detect other unusual energy paroxysms, including the inflammation of a rock from space as it enters our atmosphere.

Appearing March 30 in the form of a very small bluff ephemeral, it seems that the GLM has detected a meteor illuminating the sky over Florida before it disappears quickly. In some sequences, the meteor seems to burn with a green hue, suggesting that it contained a decent amount of nickel, a common component of many meteors and meteorites.

GOES-16 is cooperated by NASA and the National Oceanic and Atmospheric Administration, which manages the National Meteorological Service. In short, this is how the weather observers confirmed the presence of a meteor, whereas it was a little outside their usual attributions.

To be fair, this is far from the first foray of the NWS into the meteoric joke. Back in January 2018, they informed the Twittersphere that a burning ball had been detected in the sky over Michigan. In this case, the air barrier has sufficiently shaken the ground to register as a magnitude 2.0 earthquake& nbsp; on & nbsp; from the United States Geological Survey wonderfully sensitive seismometers.

NASA website, near Earth object record fireballs – and gives estimates of their trajectories and their energies released – when they are detected, but it does not seem that the fire in the sky of Floridian was recorded. This could be because the "fireball"Moniker only applies to an exceptionally bright meteor, and this one could have been brilliant, but maybe not this gloss.

I will come back in a few moments to see if it actually appears. For now, consider this meteor as all of these documentations: as an additional reminder of the inner solar system. prolonged pandemonium, one in which ping-pong balls of different sizes are almost continuously break.

Every day, about 60 tons of space dust come from meteors, comets, etc. fall on the Earth. However, as it is so beautiful, you must be incredibly fortuitous and incredibly cautious.

Their ignition, however, means that unlike all these interplanetary films, we can spot meteors if they fall in the right place.

As the Bering Sea meteor showed last December, even large meteors can go unnoticed when they burn away from the eyes of the people. This particular space rock, which emitted 173 kilotonnes of TNT energy when it exploded for 26 kilometers over isolated rivers, was only seen through a variety of mechanical sensors and satellites, which have detected his low frequency boom and the smoke process he has left behind.
