Australia; O. Trondal, Oslo, Norway; and M. Schwartz, Patagonia, AZ, report the discovery of an apparent supernova on unfiltered CCD frames taken with the 0.35-m Tenagra telescope at Perth on Apr. 19.51 (at mag 17.7) and 26.48 UT (mag 17.5) in the course of the Tenagra Observatory Supernova Search. SN 2006bs is located at R.A. = 10h26m53s.61, Decl. = -3o42'51".0 (equinox 2000.0), which is 10".5 east and 3".9 south of the center of MCG +00-27-14 (which itself has position end figures 52s.91, 47".1). Nothing was visible at the position of 2006bs on an image taken by Luckas on Apr. 3.51 (limiting magnitude about 18.0). A. V. Filippenko and R. J. Foley (University of California, Berkeley) report that inspection of a low-quality CCD spectrum (range 320-920 nm), obtained through thick clouds on Apr. 27 UT with the Keck I 10-m telescope (+ LRIS), shows that the object is a type-II supernova. The H-alpha line is dominated by the emission component, but the other Balmer lines exhibit typical P-Cygni profiles.
