---------------------------------------------------------------------------— SN 2009 UT R.A. (2000.0) Decl. Mag. ---------------------------------------------------------------------------— 2009ew May 16.33 16 38 59.85 +17 58 58.1 18.7 ---------------------------------------------------------------------------—

Further observations of 2009ew were taken with the Palomar 1.5-m telescope (May 23) and the Plaskett 1.82-m telescope (May 20, 21, and 25) using Gunn filters, yielding the following magnitudes: May 20.26 UT, g = 18.8, r = 18.8; May 21.28, g = 18.7, r = 18.7; May 23.47, g = 18.7, r = 18.7, i = 19.1; May 25.4, g = 18.8, r = 18.7. A confirming spectrogram (range 400-900 nm) of 2009ew was taken with the BTA 6-m telescope on May 17 UT; with the aid of the Supernova Identification code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), 2009ew was found to be a type-Ia supernova, most similar to SN 2003du at seven days before maximum, at redshift z = 0.09.
