UPDATE JANUARY 24
On CBET circular No. 2142, H. Maehara (Kyoto University) reports that a low-resolution spectrogram (range 400-800 nm) of the possible nova was obtained on Jan. 23.887 UT with the 25-cm telescope of the Kwasan Observatory. The spectrum shows H_alpha, H_beta, and Fe II emission lines. These features suggest that this object is a "Fe II"-class nova.
