D. Rich, Hampden, ME, reports his discovery of an apparent supernova (mag about 15.6) on unfiltered CCD frames taken with a 0.31-m reflector on Mar. 27.08 and 27.99 UT. The new object is located at R.A. = 11h52m48s.07, Decl. = +44o06'18".4 (equinox 2000.0), which is about 15" west and 56" south of the center of NGC 3938.
