Gray, Stillwater Lake, NS, Canada, report their discovery of an apparent supernova (mag about 17.0) on an unfiltered CCD image (cf. IAUC 8462) taken on Sept. 6.016 UT, with a confirming image showing the new object at mag about 16.3 on Sept. 13.015. SN 2005ea is located at R.A. = 11h06m47s.89, Decl. = +57o41'07".5 (equinox 2000.0), which is about 14" west of the nucleus of the galaxy MCG +10-16-61. Nothing is visible at this location on their images taken on Apr. 22 (limiting mag about 17.7), June 6 (limiting mag about 18.5), and Aug. 18 (limiting mag about 17.8), and nothing is present on Digitized Sky Survey images from 1994 (limiting red mag about 21.0) and 1988 (limiting blue mag about 20.5).
