SUPERNOVA 2009ls IN NGC 3423
     Koichi Nishiyama, Kurume, Fukuoka-ken, Japan; and Fujio Kabashima,
Miyaki-cho, Saga-ken, Japan, report their discovery of an apparent supernova
(mag 15.1) on seven unfiltered 30-s CCD frames (limiting magnitude 20.3) taken
around Nov. 23.779 UT using a 0.40-m f/9.8 reflector.  The new object, which
was confirmed at mag 15.3 on ten frames taken on Nov. 24.814 (limiting mag
19.8), is located at R.A. = 10h51m14s.58 +/- 0s.01, Decl. = +5d50'58".8 +/-
0".1 (equinox 2000.0), which is 3" east and 35" north of the center of the
galaxy NGC 3423.  Nothing is visible at this position on their past frames
taken on 2008 Jan. 7.762 (limiting mag 19.3) and 16.740 (limiting mag 20.1)
or on the Digitized Sky Survey (red and infrared plates).
