A. V. Filippenko and R. J. Foley, University of California at Berkeley (UCB), report that inspection of CCD spectra (range 330- 1000 nm), obtained by T. Treu and M. A. Malkan on Oct. 1 UT with the Shane 3-m reflector at Lick Observatory, reveals that SN 2004es (IAUC 8412) is of type II, perhaps 1-2 months past maximum brightness. The H_alpha line has little or no absorption component, but the emission component is strong and broad. Na I D and some Fe II lines have P-Cyg profiles. SN 2004et (IAUC 8413) is also of type II, confirming the classification derived from the high- resolution spectrum reported on IAUC 8413. The P-Cyg profile of H_alpha is greatly dominated by the emission component, but the other hydrogen Balmer lines have more typical P-Cyg profiles. The continuum is quite blue, although it plummets shortward of 400 nm. Narrow interstellar Na I D and Ca II H and K absorption lines are prominent.
