APPARENT NOVA IN M31:  M31N 2010-01a
     V. Burwitz, W. Pietsch, and M. Henze, Max-Planck-Institut fuer
Extraterrestrische Physik; A. Updike, Clemson University; P. Milne and G.
Williams, University of Arizona; D. H. Hartmann, Clemson University; J.
Rodriguez, Observatorio Astronomico de Mallorca (OAM); and S. Holmes, U.
Kolb, and R. Lucas, The Open University (TOU), report the discovery of an
apparent nova in M31 on two sets of ten 60-s stacked R-band CCD images
obtained with the robotic 60-cm telescope (+ E2V CCD camera) of the
Livermore Optical Transient Imaging System (Super-LOTIS, located at Steward
Observatory, Kitt Peak).  The new object has steadily brightened, as
indicated by the following R-band magnitudes:  Jan. 11.13 UT, 17.6; 12.092,
16.3; 13.094, 15.9.  M31N 2010-01a is located at R.A. = 0h42m56s.73 +/-
0s.03, Decl. = +41d17'21".2 +/- 0".3 (equinox 2000.0), which is 140" east
and 73" north of the core of M31.  M31N 2010-01a was also detected at red
mag 16.5 on eleven 120-s stacked unfiltered images obtained with the 0.35-m
f/11 TOU/OAM PIRATE Schmidt-Cassegrain telescope (+ SBIG STL-1001E CCD
camera) at Costitx, Mallorca, on Jan. 11.77.  (All magnitudes were derived
from a photometric solution using R magnitudes of the Local Group Survey M31
catalogue of Massey et al. 2006, A.J. 131, 2478.)  No object is visible at
the position of M31N 2010-01a on a Super-LOTIS image from Jan. 9.09 UT
(limiting R magnitude 18.5).
