S. Nakano, Sumoto, Japan, reports the discovery by Yoji Hirose (Tsutsumi, Chigasaki, Kanagawa-ken, Japan) of an apparent supernova (mag 16.7) on unfiltered CCD frames (limiting magnitude 17.5) taken on Dec. 22.784 UT using a 0.35-m f/5.7 Schmidt-Cassegrain reflector (+ SBIG ST9XEi camera). The new object is located at R.A. = 12:47:14.42, Decl. = -10:03:47.3 (equinox 2000.0), which is 18" west and 1" north of the center of the galaxy NGC 4682 (whose center is measured at position end figures 15s.6, 48".5). Nothing is visible at this position on the Digitized Sky Survey (no date or bandpass provided). The variable was designated PSN J12471442-1003473 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011jh based on the spectroscopic confirmation reported below. Additional unfiltered CCD magnitudes for 2011jh: Apr. 24, [17.5 (Hirose); Dec. 23.761, 15.7 (T. Noguchi, Katori, Chiba-ken, Japan; 0.23-m f/6.3 Schmidt-Cassegrain reflector + BITRAN BT-11E camera; limiting magnitude 17.5; position end figures 14s.41, 46".3; offset 16" west, 2" north; communicated by Nakano; image posted at URL http://park8.wakwak.com/~ngc/images/PSNinNGC4682.jpg); 24.838, 16.0 (Hirose).
