Reichart, K. Ivarsen, J. Haislip, A. Crain, D. Foster, M. Nysewander, and A. LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 17.9) on an unfiltered image taken on Oct. 15.35 UT with the 0.41-m 'PROMPT 1' telescope located at Cerro Tololo. The new object is located at R.A. = 8:02:28.39 ± 0".2, Decl. = +9:23:40.9 ± 0".2 (equinox 2000.0), which is about 55" east and 68" south of the center of the galaxy NGC 2513; nothing is visible at this position on stacked archival images taken between Jan. 8.13 and Mar. 19.04 (limiting mag 19.5), but 2010ja is visible at mag approximately 18.0 on images taken on Oct. 16.34 and 17.33.
