We present in this note a first set of events recorded from June to August 2012 by the engineering hexagon of the AMIGA moun detector. Up to August 30th, 8423 T5 events were successfully acquired by surface infill stations and their 10 m2 buried scintillator companions. Among these, 246 showers were simultaneously observed by fluorescence, surface, and muon detector systems generating the very first hybrid events of this kind. A preliminary estimation of muon detector signal at a reference distance of 450 m is analysed.
