Confirming spectrograms (range 370-730 nm) of 2009dy and 2009dw were taken with the BTA 6-m telescope on Apr. 23 UT; with the aid of the Supernova Identification code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), 2009dy is found to be a type-Ia supernova at z = 0.089 and is most similar to SN 1994ae at six days after maximum, while 2009dw is a type-IIP supernova at z = 0.042 and is most similar to SN 2004et at 15 days after maximum. Confirming spectrograms (range 380-680 nm) of 2009dx, 2009dv, and 2009du were taken with the Palomar 5-m telescope (+ DBSP) on Apr. 29. SN 2009dx is a type-Ia supernova at z = 0.042 and is most similar to SN 2003du at one day before maximum. SN 2009dv is a type-IIP supernova at z = 0.029 and is most similar to SN 2004et at ten days after maximum. SN 2009du is a subluminous type-Ia supernova at z = 0.062 and is similar to SN 1997cn at four days after maximum.
