According to IAUC No. 6731, J.-y. Hu (Beijing Astronomical Observatory) et al. reports the discovery of a new apparent bright dwarf nova. USNO 1425.09823278 19h 27m 11s.63 (J2000.0) +54o 17' 51".5 UG 13.3-19.8R R=13.3 on Aug. 31 and 13.5 on Aug. 31. Spectroscopically confirmed to be an outbursting dwarf nova. Being a large outburst-amplitude object, the variable should be an excellent target for searching for superhumps. Observations are very urgently encouraged. The object is close to galaxy UGC 11443, which may have provided a chance discovery of this dwarf nova during the supernova survey. Regards, Taichi Kato
