M. Uemura and A. Arai, Hiroshima University, report that they performed a time-series observation of this new variable between Dec. 18.5635 and 18.7895 UT with the "KANATA" 1.5-m telescope at Higashi-Hiroshima Observatory. The object was at V = 15.17 and J = 15.01 on Dec. 18.65324 and 18.65181, respectively. The light curves clearly show periodic modulations with amplitudes of about 1.2 mag in both the V and J bands. The period is estimated to be 0.0530(3) day. In conjunction with the blue color (V-J = +0.16), this observation strongly indicates that it is a SU UMa-type dwarf nova, with the observed modulations being superhumps. The superhump period is the shortest among known systems.
