Supernova 2004A in NGC 6207
Abstract
S. Nakano, Sumoto, Japan, reports the discovery by K. Itagaki (Teppo-cho, Yamagata, Japan) of an apparent supernova (mag 15.7) on several 30-second unfiltered CCD frames taken with a 0.28-m f/10 reflector on Jan. 9.84 UT. Itagaki found the new object at mag 15.7 on a confirming image taken on Jan. 10.75. SN 2004A is located at R.A. = 16h43m01s.90, Decl. = +36o50'12".5 (equinox 2000.0), which is approximately 22" west and 17" north of the center of NGC 6207 (noting that the center of the galaxy is very difficult to define). Nothing was visible at this position on Itagaki's CCD frames taken on 2000 Aug. 8, 2002 May 2, and 2003 Feb. 13 (limiting mag 18.5), or on his image from 2003 Dec. 27 (limiting mag 18). Nakano reports that SN 2004A was also observed at mag 15.7 on an unfiltered CCD image taken by R. Kushida (Yatsugatake South Base Observatory, 0.40-m f/10 reflector) on Jan. 9.877; from this image, Y. Kushida measured position end figures 01s.90, 12".3 for the new object.
