SN2001dk – discovery

Tom Boles

SN2001dk in UGC 913, discovered 2001 July 29. IAU Circular 7675 : G.M. Hurst, Basingstoke, England, reports the discovery of an apparent supernova (mag 15.6) by T. Boles (Coddenham, England) on an unfiltered CCD image (limiting mag about 18.5) secured for the UK Nova/Supernova Patrol on July 29.959 UT with a 0.36-m Schmidt–Cassegrain telescope. Nothing was visible on Boles’ CCD image from 1999 Sept. 22 (limiting mag. 18.5). The new object is located at RA 1h 22m 14s.59, Dec +34º 40' 11".3 (equinox 2000.0), which is 5" west and 3" north of the nucleus of UGC 913. M. Armstrong (Rolvenden) confirmed the presence of SN2001dk at about the same brightness on a CCD image taken on July 31.039, which yielded the following position end figures: 14s.50, 11".4.
