S. Nakano, Sumoto, Japan, reports the discovery by R. Kushida, Yatsugatake South Base Observatory, of an apparent supernova (mag 15.6) on numerous unfiltered CCD survey frames taken around May 24.70 UT with a 0.40-m Schmidt-Cassegrain reflector. A follow-up image by Kushida on May 25.77 showed the new object at mag 15.3. SN 2004bv is located at R.A. = 20h25m06s.34, Decl. = -24o48'53".7 (equinox 2000.0; measured by Y. Kushida), which is 3".8 west and 20".7 south of the center of NGC 6907. Nothing is visible at this location on earlier frames of this field back to 1995 by R. Kushida, the most recent from 2003 July 24 (limiting mag 19).
