  The MicroBooNE detector has recently completed its first year of neutrino
beam data-taking in the Booster Neutrino Beam at Fermilab, having collected
approximately half of its intended data ($3.4\times10^{20}$ of
$6.6\times10^{20}$ protons on target). We present kinematic distributions of
neutrino interactions observed from a small subset of this data (equivalent to
$5\times10^{19}$ protons on target), both as a first step towards a
charged-current muon neutrino cross-section on argon, and as an exploration of
the capabilities and operational challenges of large liquid argon time
projection chambers as neutrino detectors. These distributions have been
assessed using fully automated event selection and reconstruction.
