The detectors of
the SMART project
, of the
Institute of Astrophysics of Andalusia
(IAA-CSIC), from the astronomical observatories of
Seville
,
La Sagra
and
Sierra Nevada
(Granada) and
La Hita
(Toledo) have registered the passage of a fireball between the coasts of Spain and Algeria at 145,000 km / hour.
According to the analysis of the principal investigator of
the SMART project
,
José María Madiedo
, from the Institute of Astrophysics of Andalusia (IAA-CSIC), the fireball was recorded at dawn from Saturday to Sunday at 3:45 a.m. and due to its high luminosity, it could be seen from all over the south and center of the Iberian Peninsula
The phenomenon occurred when
a rock from a comet
entered the Earth's atmosphere
at a speed of about 145,000 kilometers.
The collision with the atmosphere at this enormous speed caused
the rock to become incandescent
, generating a fireball that began at an altitude of about 106 kilometers above the Mediterranean, at a point located about 80 kilometers away from the Andalusian coast. and 70 kilometers away from the Algerian coast.
From there the fireball advanced in a southwesterly direction
to finally extinguish itself at an altitude of 70 kilometers above the sea
;
the fireball traveled a total distance of about 38 kilometers in the atmosphere.
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.
