The closest and brightest supernova in some time has been discovered in Messier 82.
Right now it's at 11.7 magnitude, but that may increase in the next few days.
M 82 is a starburst galaxy about 12 million light-years away in the constellation Ursa Major (aka The Big Dipper).

Event: Supernova in M82 (Ursa Major) = PSN J09554214+6940260
Discovery by: Stephen J. Fossey (University College London Observatory)
Discovery magnitude: 11.7 V
Discovery date: 2014 January 21.81 UT
Coordinates: R.A. = 09 55 42.15, Decl.= +69 40 25.8 (2000.0)
PSN J09554214+6940260 is offset 54" west, 21" south from the nucleus of M82
Spectra: PSN J09554214+6940260 is a reddened young Type-Ia supernova discovered before maximum, according to a report by Y. Cao (Caltech), M. M. Kasliwal (Carnegie/Princeton), A. McKay (UT Austin), and A. Bradley (APO) on behalf of the intermediate Palomar Transient Factory Collaboration of spectra obtained on 2014 Jan. 22.305 UT using the Dual Imaging Spectrograph on the ARC 3.5m telescope (ATel #5786, http://www.astronomerstelegram.org/?read=5786). They also report the best superfit match is SN2002bo at -14d, and that the supernova has a red continuum and deep Na D absorption.
