2012CBET.3278....1D

A. Dimai, Cortina d'Ampezzo, Italy, reports his discovery, in the course of the Italian Supernovae Search Project (ISSP), of an apparent supernova (mag about 16.5) on two unfiltered CCD images (limiting mag about 18.0) taken with the 0.28-m telescope of the Col Drusci Observatory on Oct. 7.960 UT. The new object is located at R.A. = 0:37:39.38, Decl. = +10:21:29.0 (equinox 2000.0), which is 6" west and 1" north of the nucleus of the galaxy IC 35. ISSP images of the same field taken on Sept. 24.9 (limiting mag about 18.0) showed nothing at this position, nor do Palomar Sky Survey infrared, red, and blue plates. The variable was designated PSN J00373938+1021290 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012fs based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012fs (unfiltered unless noted otherwise): Oct. 8.935, 16.5 (Dimai; limiting mag about 18.0; Takahashi TOA-150 telescope at the Nerpio Observatory in Spain); 9.224, 16.3 (Planewave 43-cm CDK telescope, Mayhill, NM, U.S.A.; image posted at URL http://www.cortinastelle.it/PSNJ00373938_1021290_20121009.jpg); 10.211, 17.4 (J.
