APPARENT NOVA IN M31:  M31N 2010-12b

Several independent reports of a discovery of an apparent nova in M31

— designated M31N 2010-12b — have been received, as detailed below.

M. Koishikawa, Sendai Astronomical Observatory, reports that he found

the new object on a CCD image taken with a 1.3-m f/4.85 reflector on Dec.

10.532 UT.W. Pietsch, M. Henze, and V. Burwitz, Max-Planck-Institut fuer

Extraterrestrische Physik); A. Kaur and D. H. Hartmann, Clemson University;

and P. Milne and G. Williams, University of Arizona, report the discovery of

M31N 2010-12b on twelve stacked, 60-s 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 on Kitt Peak, on

Dec. 11.095 UT; they measure the new object to be 149″ west and 672″ north of

the center of M31.Koichi Nishiyama (Kurume, Japan) and Fujio Kabashima (Miyaki, Japan)

report their discovery of M31N 2010-12b on ten 40-s unfiltered CCD frames

(limiting magnitude 19.8) taken around Dec. 11.468 UT using a Meade

200R 0.40-m f/9.8 reflector (+ SBIG STL1001E camera).  The new object is

lcated 149″ west and 672″ north of the center of the galaxy M31.

Guoyou Sun (Wenzhou, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang,

China) report their discovery of M31N 2010-12b at mag approximately 17.7 on

several unfiltered 60-s survey CCD images (limiting mag about 19.0) taken by

Xing Gao in the course of the Xingming Observatory Sky Survey at Mt. Nanshan

around Dec. 11.517 UT using a Celestron C14 0.36-m f/6.9 Schmidt-Cassegrain

telescope.Gao found a pre-discovery from Dec. 10.515.  T. Yusa, Osaki, Japan, also

reports a pre-discovery unfiltered CCD image (from twelve co-added 90-s images;

limiting magnitude 19.0) of M31N 2010-12b on Dec. 10.359 using a 0.30-m f/7

Cassegrain telescope (+ SBIG STL-1001E) at the Osaki Lifelong Learning Center.

Yusa’s image is posted at the following website URL:
