2005IAUC.8475....1N

S. Nakano, Sumoto, Japan, reports the discovery by Yoji Hirose (Chigasaki, Kanagawa-ken, Japan) of an apparent supernova (mag 15.2) on eight unfiltered CCD frames taken on Feb. 1.442 UT with a 0.35-m f/6.8 Schmidt-Cassegrain reflector. Nakano has measured the position of SN 2005W from one of Hirose's images: R.A. = 1h50m45s.75, Decl. = +21o45'35".6 (equinox 2000.0), which is 56" east and 1" south of the center of NGC 691. Hirose adds that nothing is visible at this location on frames taken by himself on Jan. 11, 21, and 24 (limiting mag 16.5-17) or on Digitized Sky Survey images. There is also a foreground star of mag 17.6 at position end figures 45s.46, 38".6. W. Li, University of California, reports that a KAIT image taken on Feb. 2.18 shows the new object at mag 14.7, but nothing was visible at this location on a KAIT image from Jan. 23.20 (limiting mag 19.0); Li provides position end figures 45s.77, 35".4 for SN 2005W.
