Folatelli, M. Hamuy and N. Morrell, Carnegie Supernova Project, report that CCD spectra (range 385-910 nm) obtained on Sept. 14 UT with the Las Campanas du Pont 2.5-m telescope (+ WFCCD spectrograph) reveal that SN 2004dz (IAUC 8395), SN 2004ee (IAUC 8399) and SN 2004ea (IAUC 8396) are evolved type Ia supernovae, a few months past maximum. They confirm the report on IAUC 8404 that SN 2004dy is a type II supernova with broad H-alpha, but they detect a strong He I 5876-nm emission atop a blue continuum, and this suggests a young supernova. SN 2004ej (IAUC 8405) is of type II with a prominent H-alpha P-Cyg profile, the velocity inferred from the absorption minimum of H-beta being 6400 km/s (assuming the 2723 km/s recession velocity from NED database); both the expansion velocity and the presence of Fe II 516.9-nm suggest that this supernova exploded 20-30 days ago.
