We report the discovery of a possible classical nova located toward the Galactic bulge in data from the Optical Gravitational Lensing Experiment (OGLE) sky survey.

The nova is located at equatorial coordinates (RA, DEC) = (17:49:57.33, -29:14:37.9) J2000.0. It was discovered in the image obtained on 2016 July 12.2104 UT at an I-band magnitude of 14.77 mag. It was invisible in the earlier image from July 10.23946 UT. In the latest frame, which was acquired on 2016 July 15.29597 UT, it brightened to I = 13.77 mag.

The nova progenitor is invisible in the OGLE reference frames, meaning it was fainter than I = 21.2 mag. The nova may be heavily reddened. According to the VVV reddening maps (Gonzalez et al 2012, A&A 543, 13), the interstellar reddening in the 2x2 arcmin region around the nova is E(J-Ks) = 2.05 +/- 0.52 mag.

Follow-up observations are encouraged.
