Discovered on frames by Y. Sakurai, Mito, Japan, using Nikon D7100 digital camera + 180-mm f/2.8 lens. Nothing is visible at this location on two frames (limit mag.= 11.0) taken on 2016 Oct. 23.398 UT.

This probable nova was already reported as ASASSN-16ma (R.A. 18h20m52.12s, Decl. -28°22'13.52", J2000.0) by Krzysztof Stanek et al. in ATel #9669 (issued on 26 Oct 2016 at 01:28 UT). Quote: "ASASSN-16ma was discovered in images obtained on 2016-10-25.02 at V~13.7 and proceed to brighten to V~11.6 a day later (UT 2016-10-26.02). We do not detect (V>17.3) the object in images taken on UT 2016-10-20.04 and before. No previous outbursts are detected at this location since ASAS-SN started observing the Galactic center in March 2016."
