Kinugasa, Gunma Astronomical Observatory; and H. Yamaoka, Kyushu University, report that a low-resolution spectrum (range 400-800 nm) of the possible dwarf nova in Hydra that was reported on CBET 1225, taken on Jan. 27.7 UT with the Gunma 1.5-m telescope (+ LRS), shows a blue continuum with the Balmer lines in absorption. The H_alpha absorption is filled by the emission component. This confirms that the object is a dwarf nova in outburst.
