Neutrino oscillation experiments have opened a window on physics beyond the standard model. The next chapter in this unfolding story is the use of neutrino oscillations to determine the neutrino mass hierarchy and the extent of CP violation in the lepton sector. NOvA is a long baseline neutrino oscillation experiment that generates neutrinos at Fermilab and measures their interactions in a near detector at Fermilab and a 14 kiloton detector located in Northern Minnesota. The detector is almost complete and commissioning data is being taken with both cosmic rays and neutrinos from Fermilab. This talk will describe the detector’s properties and its construction as well as the current status of commissioning.
