NOVA IN M31

E. Halderson, T. Shefler, M. Modjaz, J. Y. King, M. Papenkova, W. D. Li, R. R. Treffers, and A. V. Filippenko, University of California at Berkeley, report their discovery of an apparent nova in M31 (NGC 224) during the course of the Lick Observatory Supernova Search (cf. IAUC 6627) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT). The nova was found and confirmed (unfiltered mag 17.8) on unfiltered CCD images taken on Sept. 15.3 and 16.3 UT, respectively. The object is located at R.A. = 0h42m46s.6, Decl. = +41o14'50" (equinox 2000.0; due to a lack of nearby stars, this semiaccurate position was calculated as an offset from the NED position for the nucleus of M31), which is about 26" east and 78" south of the galaxy nucleus. A KAIT image of M31 taken on Aug. 31.3 showed nothing at the position of the nova (limiting mag about 19.0).
