Abstract (from CDS):

M. Hamuy, Carnegie Observatories, reports that a spectrum (range 380-730 nm) of SN 2002eq (cf. IAUC 7959), obtained on Sept. 12.17 UT with the Las Campanas Dupont 2.5-m telescope (+ Modular Spectrograph), shows it to be a type-Ia supernova. The spectrum bears strong resemblance to SN 1994D at 20 days past maximum; a redshift of approximately 0.088 is derived by comparison to SN 1994D. A spectrum of SN 2002ez (cf. IAUC 7967), obtained on Sept. 12.27, bears resemblance to the type-Ia SN 1994D at 18 days past maximum; a redshift of approximately 0.043 is derived by comparison to SN 1994D. A spectrum of SN 2002fa (cf. IAUC 7967), obtained on Sept. 12.08, shows it to be of type II with a broad H_alpha line exhibiting a P-Cyg profile. The minimum of the absorption component yields an expansion velocity of 8100 km/s. A spectrum of the nucleus of the host galaxy yields a redshift of 0.060.
