My following comments are based on Kiyota-san's astrometry result. VVV J161432.86-533014.38 (position end figures 32.86s, 14.4"; Jmag. 18.8, Ksmag. 17.3) is 0.6" away. Update: Nothing was detected at the transient's position by the ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) since 2016 Mar. 10; latest observation is 2018 Sept. 24.0695 UT, gmag. fainter than 15.8; complete 'light curve' at https://asas-sn.osu.edu/light_curves/1b48518e-f6ac-407d-8eb1-8a38d70919cb --- Patrick Schmeer (Saarbr├╝cken-Bischmisheim, Germany)
