Supernova 2001dn in NGC 662

G. M. Hurst, Basingstoke, England, reports the discovery by T. Boles (Coddenham, Suffolk) of an apparent supernova (mag 15.5) on an unfiltered CCD image (limiting mag 18.5) obtained on Aug. 14.069 UT with a 0.36-m reflector. The following averaged astrometry was measured from six exposures: R.A. = 1h44m35s.32, Decl. = +37o41'49".7 (equinox 2000.0), which is 4" west and 3" north of the center of NGC 662. SN 2001dn is also present on unfiltered CCD images taken on Aug. 14.870 (by Boles; mag about 15.5) and 15.003 (by M. Armstrong, Rolvenden, Kent). SN 2001dn was not present on a Boles image taken on 1999 Oct. 16 (limiting mag 18.5) or on Palomar Sky Survey photographs taken on 1989 Nov. 18 and 1988 Sept. 13.
