Andalusia: A fireball crosses the south of the peninsula after entering the atmosphere at 72,000 km / hour
SMART project: a fireball flies over southern Spain at 54,000 km / hour
A bright ball of fire has crossed the sky of Castilla-La Mancha and Andalusia
at 6:21 am this Sunday
, a phenomenon that occurred when a rock from an asteroid entered the Earth's atmosphere at high speed (96,000 kilometers per hour ).
The phenomenon has been recorded by the detectors of the Southwest European Fireball and Meteor Network that operates at the
La Hita Astronomical Complex (Toledo)
, according to the Astrohita Foundation.
These detectors work within the framework of the SMART Project, which is coordinated by the Andalusian Institute of Astrophysics (IAA-CSIC) with the aim of continuously monitoring the sky to record and study the
impact against the earth's atmosphere of rocks
from different objects in the world. Solar system.
The fireball has also been recorded by the detectors that this same research project has installed in the observatories of
Sierra Nevada (Granada), Calar Alto (Almería), La Sagra (Granada), Seville and Madrid
(Complutense University).
This phenomenon has been analyzed by the researcher in charge of the project, the astrophysicist
José María Madiedo
, from the Institute of Astrophysics of Andalusia (IAA-CSIC), and has determined that the rock that originated this fireball entered the atmosphere at about 96,000 kilometers per hour on Andalusia, specifically on the northeast of the province of Jaén.
Due to this high speed, the sudden friction with the air caused the rock to become
incandescent at a height of about 82 kilometers
, and this incandescence was the one that generated the bright ball of fire that, due to its great luminosity, could be seen from more 500 kilometers away. The fireball, which showed a marked greenish tone, advanced in a northeast direction and flew over Castilla-La Mancha, extinguishing itself over the southwest of the province of Albacete at an altitude of about 29 kilometers.
