Greg Bock, Windaroo, Queensland, Australia, reports the discovery of an apparent supernova (mag 15.5) on a 30-s unfiltered CCD image taken on Dec. 27.552 UT using a 35-cm Meade LX200R telescope (+ ST10 CCD camera). The new object is located at R.A. = 2:58:07.60, Decl. = -10:21:54.1 (equinox 2000.0; USNO-B and UCAC3 catalogues), which is 1" west and 7" south of the nucleus of the galaxy NGC 1154. Nothing is visible at this position on Digitized Sky Survey red, blue, and infrared images (limiting red magnitude > 19). The variable was designated PSN J02580760-1021541 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011jp based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011jp (unfiltered unless noted otherwise): Oct. 31, [18.0 (Bock); Dec. 29.110, 17.1 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 07s.60, 53".3; image posted at URL http://www.flickr.com/photos/43846774@N02/6597503477/); 29.189, 15.9 (L.
