At 11:10 p.m. local time on September 13, a
fireball was detected by the Dehesa San Francisco station (UMA/SMA/Fundación
Monte Mediterráneo) and the Córdoba-Rabanales station (UMA/SMA/Agrupación
Astronómica de Córdoba), both part of the network run by the University of
Málaga and the Málaga Astronomical Society, as well as by the BOOTES-1
observatory, part of the BOOTES Global Network (IAA/CSIC).
The object, originating from the Solar System,
first became visible at an altitude of 66.8 km. It travelled 52 km in a
northeasterly direction at an average speed of 41,000 km/h before
disintegrating at an altitude of 34.8 km. This is relatively slow for this type
of event. In fact, the fireball lasted four and a half seconds, which is quite
unusual.
The cover image is a composite of four images,
which explains the fragmentation that can also be seen in the graph below,
showing how brightness varied over time.
The calculated orbit of the object had a
semi-major axis of a = 2.08 AU, an eccentricity of e = 0.52 and an inclination
of i = 5.09°.
