S. Howerton, Arkansas City, KS, U.S.A.; A. J. Drake, S. G. Djorgovski, A. Mahabal, M. J. Graham, and R. Williams, California Institute of Technology; M. Catelan, Pontificia Universidad Catolica de Chile; E. C. Beshore and S. M. Larson, Lunar and Planetary Laboratory, University of Arizona; and E. Christensen, Gemini Observatory, report the discovery of an apparent supernova in public images from the Mount Lemmon Survey (MLS):

---------------------------------------------------------------------------— SN 2011 UT R.A. (2000.0) Decl. Mag. Offset ---------------------------------------------------------------------------— 2011jk Nov. 27.39 7 25 43.05 +20 06 21.7 19.2 10".5 W, 13".7 N ---------------------------------------------------------------------------—

The variable was designated PSN J07274305+2006217 when it was posted at the Central Bureau's TOCP webpage because the right ascension was originally posted erroneously as 27' instead of the proper 25'; the variable is here designated SN 2011jk based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011jk (unfiltered unless noted otherwise): Mar. 5.20 UT, [20.6 (MLS); Nov. 28.319, 18.6 (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 43s.13, 22".0); Dec. 24.42, 19.0 (MLS).
