NOvA, is a two-detector, long-baseline neutrino oscillation experiment located at Fermilab, Batavia, IL, USA. The NOvA experiment was designed primarily to constrain neutrino oscillation parameters by analyzing $$\nu_\mu (\bar{\nu}_\mu)$$ disappearance and $$\nu_e (\bar{\nu}_e)$$ appearance data observed at the far detector. The Neutrinos at Main Injector (NuMI) beamline at Fermilab provides a high purity beam of neutrinos and anti-neutrinos to the experiment. The NOvA experiment consists of two functionally identical, finely granulated liquid tracking calorimeters, both situated 14.6 mrad off-axis to the beam direction. The NOvA near detector, situated 100 meters underground and 1 kilometer from the beam source, detects the non-oscillated $$\nu_\mu (\bar{\nu}_\mu)$$ and beam $$\nu_e (\bar{\nu}_e)$$ events. The far detector, located in Ash River, MN, USA, 810 kilometers from the beam source, records the non-oscillated $$\nu_\mu (\bar{\nu}_\mu)$$ and the oscillated $$\nu_\mu (\bar{\nu}_\mu) \to \nu_e (\bar{\nu}_e)$$ events. The most recent measurements of three flavor neutrino oscillation parameters based on an analysis of the data collected from neutrino-beam exposure of $$26.60 \times 10^{20}$$ POT and anti-neutrino beam exposure of $$12.50\times 10^{20}$$ POT including an additional low energy $$\nu_e$$ sample, will be presented in this talk.
