The detectors of the SMART project, of the Institute of Astrophysics of Andalusia (IAA-CSIC), from the astronomical observatories of Seville, La Sagra (Granada) and La Hita (Toledo) have recorded the passage of a fireball over southern Spain at 183,000 km / hour.

According to the analysis of the principal investigator of the SMART project, José María Madiedo, from the Instituto de Astrofísica de Andalucía (IAA-CSIC), the fireball It was recorded last morning at 4:02 a.m. and due to its high luminosity, it could be seen from the southern and central areas of the country..

The phenomenon has occurred when a rock from a comet enters the Earth’s atmosphere at a speed of about 183,000 kilometers per hour.

The abrupt friction with the atmosphere at that enormous speed made the rock turn incandescent, generating a fireball that began at an altitude of about 111 kilometers over the east of the province of Cordova.

It advanced in a southwesterly direction and became extinct at an altitude of about 83 kilometers above the southwest of the same province, almost on the vertical of the town of Fernán-Núñez; the fireball traveled a total distance in the atmosphere of about 35 miles.

In addition to the detectors from the SMART project, this ball has also been recorded by the detection station located in Madrid.

The SMART project detectors operate within the framework of the Southwest Europe Fireball and Meteor Network (SWEMN), which aims to continuously monitor the sky in order to record and study the impact against the Earth’s atmosphere of rocks from different Solar System objects.
