M. Hamuy and N. Morrell, Carnegie Observatories; J. Arias, Observatorio de La Plata; and R. Barba, Universidad de La Serena, report that a spectrum (range 390-900 nm) of SN 2003gr (cf. IAUC 8169), obtained on July 31.31 UT with the Las Campanas Observatory Baade 6.5-m telescope (+ Boller & Chivens spectrograph), shows it to be a type-Ia supernova. The spectrum bears strong resemblance to that of SN 1994D taken 11 days after maximum. The minimum of the Si II 635.5-nm line yields an expansion velocity of -10200 km/s (adopting the NED host-galaxy recession velocity of 7691 km/s). A spectrum of SN 2003gh (cf. IAUC 8159), taken on July 31.44, also shows it to be a type-Ia supernova. The spectrum is similar to that of SN 1994D taken 38 days past maximum. A spectrum of SN 2003gi (cf. IAUC 8161), taken on July 31.32, shows it to be a type-Ia supernova. The spectrum is similar to that of SN 1994D taken 76 days past maximum.
