Puckett and A. Langoussis report the discovery of an apparent supernova (mag 15.3) on an unfiltered CCD frame taken with the 0.60-m automated supernova patrol telescope on Apr. 17.13 UT. The new object was confirmed at mag 15.2 on CCD frames taken on Apr. 18.05. SN 2005bo is located at R.A. = 12h49m41s.03, Decl. = -11o05'47".3 (equinox 2000.0), which is 7".6 west and 12".7 south of the center of NGC 4708. Nothing is visible at this location on images taken by Puckett on 2002 Mar. 12 and 2003 Mar. 24, (limiting mag about 20.0). SN 2003ef also occurred in NGC 4708 (cf. IAUC 8131).
