The Micro Booster Neutrino Experiment (MicroBooNE) is designed to explore the lowenergy excess in the νe event spectrum reported by the MiniBooNE experiment [1] and to measure ν-Ar cross sections in the 1 GeV energy range. The detector is a liquid argon time projection chamber with wire readout, supplemented with a light detection system based on photo-multiplier tubes (PMTs). The apparatus is located in the Booster Neutrino Beamline (BNB) at Fermilab and started collecting neutrino data in October 2015. This note presents a study of the stability of the MicroBooNE detector by measuring the average number of reconstructed tracks per event, the average number of reconstructed vertices per event, and the average number of multi-PMT coincidences (flashes) per event. These quantities are chosen since these are the most relevant to the νµ charged-current inclusive analysis [2].
