On UT 2008 Nov 19.536, P60-FasTING (Palomar 60-inch Fast Transients In Nearby Galaxies) discovered a possible nova in M82 at RA(J2000) = 09:55:58.390 DEC(J2000) = +69:40:56.17, offset from the nucleus by 29.5"E, 10.4"N. P60-M82-081119 had a brightness of g = 20.0 +/- 0.1 at peak corresponding to Mg = -7.8 at the distance of M82 (uncorrected for extinction). There is no counterpart in SDSS or SIMBAD. It is not detected to g > 21.4 (3-sigma upper limit) on Nov 13.482. It has a color of g-i = 1.0. Follow-up spectroscopy is encouraged and finder chart is available at: http://www.astro.caltech.edu/~mansi/P60FasTING/Atel/
