S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki (Teppo-cho, Yamagata, Japan) of an apparent supernova (red mag 16.7) on numerous unfiltered CCD frames taken around Feb. 5.638 UT with a 0.30-m f/7.8 reflector. The new object is located at R.A. = 12h41m05s.18, Decl. = +50o22'56".2 (equinox 2000.0), which is 7" west and 40" south of the center of NGC 4617. Nothing was visible at this location on CCD frames taken by Itagaki back to 2001 (limiting mag 19.5) or on the Digitized Sky Survey. Nakano adds that K. Kadota (Ageo, Saitama-ken, Japan) has confirmed the presence of a new star (mag 16.8) at position end figures 05s.19, 55".8 on a CCD frame taken with a 0.25-m reflector on Feb. 5.771.
