During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the quadruple 14-cm "Cassius" telescope in Cerro Tololo, Chile, we detect a new transient source, most likely a classical nova, near the Galactic center

ASASSN-16kd was discovered in images obtained on UT 2016-09-07.003 at V~11.4 mag, and we also have a detection of this transient on UT 2016-09-06.00 at V~12.1. We do not detect (V>17.4) the object in images taken on UT 2016-09-02.99 and before. No previous outbursts are detected in the previous 81 epochs of ASAS-SN data at this location since ASAS-SN started observing the Galactic center in March 2016.
