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