The project detectors SMART, from the Institute of Astrophysics of Andalusia (IAA-CSIC), from the astronomical observatories Calar Alto (Almería), La Sagra (Granada), La Hita (Toledo), Sierra Nevada (Granada) and Seville have recorded the passage of a fireball over southern Andalusia at 39,000 kilometers per hour.

As reported by the principal investigator of the SMART project, Jose Maria Madiedo, from the Institute of Astrophysics of Andalusia (IAA-CSIC), the fireball was recorded at 11:55 p.m. on Friday, September 25.

The phenomenon has occurred when entering the Earth’s atmosphere a rock from an asteroid at a speed of about 39,000 kilometers per hour.

The collision with the atmosphere caused the rock to turn incandescent and generate a fireball that started at an altitude of about 80 kilometers over the northeast of the province of Seville; from there it advanced in a northeast direction, entering Córdoba and dying out at an altitude of about 26 km above the northwest of this other province.

The detectors of the SMART project 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.
