We report near-infrared J-, H-, and K-band photometry of the Nova Oph 2012 No.2 (CBET # 3124). The epochs of our observations, filters used and the magnitudes derived are given in the table below. The preliminary reduction shows the declining trend of the nova brightness in J, H and K bands. The observed near-IR colors are consistent with the large interstellar extinction seen in the direction of the nova as reported by Walter F.M. in CBET # 3124.
