LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 16.4 ± 0.2) on an R-band image taken on Dec. 15.16 UT with the 0.41-m 'PROMPT 4' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 17.1 ± 0.3 in an image taken on Dec. 6.17, is located at R.A. = 2h43m20s.80 ± 0".1, Decl. = +4o58'19".1 ± 0".1 (equinox 2000), which is about 22" west and 13" north of center of the galaxy NGC 1070. Nothing is visible at this position on archival images taken on Nov. 19.11 and 26.12 (limiting mag 18.0).
