POSSIBLE SUPERNOVA PSN K1004-1
     T. Kryachko, A. Prokopovich, and B. Satovskiy, Kazan State University
(KSU), report the discovery of a possible supernova (mag approximately 19.5)
on five unfiltered images (limiting mag 21.5) obtained on Mar. 19.75 UT and
three on Mar. 20.74 UT with the Takahashi FRC-300 telescope (+ Apogee Alta
U9000 CCD camera) at the KSU's Astrotel Observatory at Karachay-Cherkessia,
Russia.  The new object, designated PSN K1004-1, is located at R.A. =
12h39m48s.34 +/- 0".1, Decl. = +5d15'43".0 +/- 0".1 (equinox 2000.0), which
is about 9" west and 10" north of the center of the galaxy 2MASX
J12394896+0515331.  Nothing is visible at this position on a Palomar Sky
Survey image taken on 1991 Jan. 14 (limiting blue mag 21.5).  B. Rizhyn
reports confirmation of PSN K1004-1 at approximate unfiltered CCD magnitude
19.5 on six images obtained remotely on Mar. 21.35 with a 0.4-m f/9
Ritchey-Chretien telescope at the Tzec Maun Observatory in New Mexico,
providing position end figures 48s.33, 43".1, adding that nothing is
visible at this position on Digitized Sky Survey blue and red images
(no dates or limiting magnitudes provided).  The discovery image has been
posted at website URL http://www.makhaon.com/_files/sn_march_20_74UT.gif.
