Abstract
Y. L. Qiu, Q. Y. Qiao, and J. Y. Hu, Beijing Astronomical Observatory (BAO), report their discovery, in the course of the BAO Supernova Survey, of an apparent supernova (mag about 16.0) in NGC 7714. SN 1999dn was discovered on two unfiltered CCD images taken on Aug. 19.76 and 19.82 UT with the BAO 0.6-m telescope, and it was confirmed on Aug. 20.65 with the BAO 0.60-m Schmidt telescope by X. Zhou and Z. Zheng. The new star is located at R.A. = 23h36m14s.70, Decl. = +2 09'08".8, which is 9".9 east and 9".4 south of the center of NGC 7714. This is a bright foreground star near NGC 7714. CCD frames taken on Aug. 10 (limiting mag about 18.0) show no object at the position of the supernova.
