We obtained an optical spectrum (range 390-860 nm) for the transient AT 2018hrg (=KAIT-18ay) in galaxy UGC 404, discovered by Lick Observatory Supernova Survey (LOSS), on UT Nov 01.8 2018 with the 2.16-m telescope (+BFOSC) at Xinglong Station of National Astronomical Observatories of China (NAOC). The spectrum is consistent with that of a recurrent nova like T Pyx, showing prominent narrow P-cygni line profiles of Ha and O I 7774. An expansion velocity of about 1200 km/s can be derived from the absorption minimum of Ha.
