Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 17.2) on unfiltered CCD images taken on Mar. 2.194 and 3.159 UT with a 0.35-m reflector. The new object is located at R.A. = 17h30m41s.19, Decl. = +6o16'33".1 (equinox 2000.0), which is approximately 11".9 west and 23".0 south of the center of NGC 6378. Nothing is visible at this location on Boles' images from 2005 July 16 and Aug. 29 (limiting mag 19.5) or on Digital Sky Survey plates from 1997 Apr. 12 (limiting red mag 20.5) and 1990 June 17 (limiting blue mag 21.0).
