SUPERNOVA 2009mh IN NGC 3839
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata, Japan) of an apparent supernova (mag 16.6) on unfiltered
CCD frames (limiting mag 19.0) taken on Dec. 12.779 UT using a 0.30-m f/7.8
reflector at the Takanezawa Station, Tochigi-ken.  The new object is located
at R.A. = 11h43m55s.93, Decl. = +10o46'55".2 (equinox 2000.0), which is 23"
east and 10" south of the center of NGC 3839.  Nothing is visible at this
position on the Digitized Sky Survey or on his image of NGC 3839 taken on
2002 Jan. 19 (limiting mag 19.0).  Itagaki has posted the discovery image at
website URL http://www.k-itagaki.jp/images/psn3839.jpg.  Nakano adds that
six co-added 120-s confirming unfiltered CCD images (limiting mag 18.6),
obtained by T. Yusa (Osaki, Miyagi-ken, Japan; remotely using a 0.25-m f/3.4
reflector near Mayhill, NM, U.S.A.) on Dec. 13.39, yield mag 16.7 and
position end figures 55s.93, 55".2.
