Dimai, Cortina d'Ampezzo, Italy, on behalf of the CROSS program (cf. IAUC 7373), reports the discovery by Marco Migliardi (Cortina d'Ampezzo) and Elisa Londero (Gemona, Italy) of an apparent supernova (mag about 16.8-17.3) in two unfiltered CCD images (limiting magnitude about 18.5) taken on Feb. 26.82 UT with the 0.5-m "Ullrich" telescope. Dimai obtained numerous confirming images with the same telescope during Feb. 27.77-27.78, showing 2008ao at mag about 17.4. The new object is located at R.A. = 3h07m46s.66, Decl. = +38o22'06".2 (equinox 2000.0), which is about 6" east and 11" south of the apparent host galaxy's nucleus. CROSS images of the same field taken on Feb. 10 showed nothing at this position (limiting mag about 18.5), and 2008ao does not appear on Palomar Sky Survey infrared, red, and blue plates.
