T. Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 18.9) on unfiltered CCD images taken on Aug. 19.058 UT with a 0.35-m reflector. The new object is located at R.A. = 2:00:24.84, Decl. = +24:34:43.3 (equinox 2000.0), which is approximately 19".8 east and 6".7 south of the center of IC 1764. Boles also measured position end figures 24s.85, 43".7 and magnitude V = 19.0 on Aug. 20.497 using an image taken with a 0.61-m Cassegrain reflector at the Sierra Stars Observatory, Alpine County, California (limiting mag 20.5). Nothing is present at this position on Boles's images from 2008 Feb. 10 and 2005 Aug. 28 (limiting mag 19.5) or on Digitized Sky Survey plates from 1991 Oct. 9 (limiting red mag 20.5) and 1988 Oct. 7 (limiting blue mag 21.0). J. Brimacombe, Cairns, Australia, using a remotely operated 50-cm reflector (+ STL6K camera + clear filter) at New Mexico Skies Observatory, Mayhill, NM, U.S.A., obtained a confirming image on Aug. 20.393 (limiting mag 20.5), yielding position end figures 24s.84 ± 0s.01, 43".7.
