Further to IAUC 8287, W. Li reports the LOSS discovery, on a KAIT image taken on Feb. 12.5 UT, of a supernova (mag 18.5) located at R.A. = 11h43m28s.26, Decl. = +21o40'30".3 (equinox 2000.0), which is 0".5 east and 3".3 north of the center of the apparent host galaxy. A. V. Filippenko, R. Chornock, and R. J. Foley report that inspection of CCD spectra (range 400-1000 nm), obtained on Feb. 14 UT with the Keck II 10-m telescope (+ ESI), shows that SN 2004Y is of type Ia, roughly 3-4 weeks past maximum brightness. The redshift of the host galaxy, measured from narrow emission lines from H II regions close to the supernova, is 0.0692.
