SUPERNOVA 2007bk
     H. Mikuz, Ljubljana, reports the discovery of an apparent supernova
(mag 16.5) on four unfiltered CCD images taken around Apr. 20.005 UT
with the 0.60-m f/3.3 Cichocki reflector in the course of the Comet and
Asteroid Search Program (PIKA) at Crni Vrh Observatory.  The new object
is located at R.A. = 15h28m45s.58, Decl. = +58o52'12".8 (equinox 2000.0),
which is approximately 5".0 east and 12".5 north of the center of a
nearby faint galaxy.  Nothing is visible at this location on three
consecutive unfiltered PIKA images obtained on 2005 Apr. 4.882 (limiting
mag 18.5) or on several Palomar Sky Survey and 2MASS images from the
Aladin database.  A confirming R-filtered image of 2007bk taken on Apr.
20.950 yields magnitude R = 16.65 +/- 0.02.
