On Christmas Eve, when televisions were broadcasting the first speech of King Philip VI, a fireball crossed Spain from end to end as if it were a signal coming from the sky. The fireball, which had multiple witnesses cut through the border between Murcia and Almeria and crossed the peninsula diagonally from southeast to northwest, to finish in the Atlantic, in the south of Galicia. It is of what scientists call a bolide rozador, a rock that enters the Earth’s atmosphere and then leave again and continue their journey around the Sun, published abc.es.
“The fireball was started about 105 km above the Algerian town of Tiaret, at 21.06 CET Spanish, “explains José María Madiedo, professor at the University of Huelva and member of the Spanish Research Network Fireball and Meteor. The rock, 100 kilos and barely a meter across, entered the atmosphere at a speed of 80,000 miles per hour. The entry angle was very low, did not reach the 4 degrees to the horizontal.
He entered the Peninsula along the border between Murcia and Almeria and when he was near the vertical of Ciudad Real, reached its minimum height, about 75 km above the ground. From there, the effect of low angle of his career joined the curvature of the Earth made its height was increasing. Then he spent nearly on the vertical of Ciudad Rodrigo, Salamanca, and entered Portugal. Then he flew Bayona, Pontevedra, and when he was about a hundred miles of the coast just left the Earth’s atmosphere as if it were a stone bouncing against water. In total, he traveled 1,200 miles in a minute. For these reasons, it is “a highly unusual phenomenon,” says the researcher. “The last comparable to that just note about Spain took place on March 29, 2006 on Japan, with similar brightness, distances and heights.”
The storm was not as bright as others that have been observed in the peninsular sky, but it moved very slowly, allowing the witnesses enjoy a unique spectacle. “There are people who saw the fireball while driving, had time to park, leave the car and still see the light in the sky,” says Madiedo. Furthermore, it could be widely recorded by the monitoring systems of the sky.
