abstract = {A superbolide with an estimated absolute magnitude of−20±1was seen on 2012 July 13 over
the centre and south of Spain. This extraordinary event, which was witnessed by numerous
casual observers, was recorded in the framework of the continuous fireball monitoring and
meteor spectroscopy campaign performed by the SPanish Meteor Network (SPMN). Thus,
because of optimal weather conditions, the bolide was imaged from 10 meteor observing
stations. Here we present the analysis of this magnificent event, which is the brightest fireball
ever recorded by our team. The atmospheric trajectory of the bolide and the orbit in the Solar
system of the parent meteoroid were obtained. The emission spectrum produced during the
ablation of this particle is also discussed.We found that the meteoroid, which was following a
Halley Type Comet orbit, was depleted in Na and had a tensile strength one order of magnitude
higher than that corresponding to typical cometary materials. By means of orbital analysis
tools we have investigated the likely parent body of this particle and the results suggest that
the progenitor is a damocloid. The impact area of the hypothetical remnants of the meteoroid
is also given and a search for meteorites was performed, but none was found.},
