Puckett and R. Gagliano report the discovery of an apparent supernova (mag 17.4) on two CCD images taken with a 0.35-m reflector at Ellijay, GA, on Mar. 25.105 and 25.106 UT in the course of the Puckett Observatory Supernova Search; the new object was confirmed at mag 17.3 by Puckett with a 0.60-m reflector on Mar. 26.021. SN 2006bb is located at R.A. = 8h33m31s.09, Decl. = +41o31'04".1 (equinox 2000.0), which is 3".6 east and 27".5 south of the center of UGC 4468.
