Fireball strikes over Calar Alto Astronomical Observatory during the evening twilight


This fireball got so bright that is was recorded during daytime by cameras placed on Calar Alto Astronomical Observatory in Spain.

The meteor strike, most probably produced by the impact of a cometary meteoroid with the atmosphere, occurred 7 July, 2015 at 20:01 UT.

Spotting a daylight meteor is considered to be quite rare, due to the energy required to light up the sky when competing with the sun.

The main difference with night-time meteors, known widely as shooting stars, is the size. Meteor visible at night could be as small as a grain of sand or an apple pip.

The fireball was probably about the size of a walnut, up to the size of a cricket ball.

Any booms heard?
