L. Prieto, Carnegie Observatories; and N. Morrell, Las Campanas Observatory, report that they obtained optical spectra (range 380-920 nm; resolution 0.8nm) of 2010ll (cf. CBET 2602) and SN 2010lp (cf. CBET 2612), as well as the possible supernova reported on CBET 2611, on Dec. 30-31 UT with the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. The SNID cross-correlation software (Blondin and Tonry 2007, Ap.J. 666, 1024) was used to aid identification and age/redshift estimation. SN 2010ll is a normal type-Ia supernova at approximately 20 days after maximum; the redshift obtained with SNID from the supernova features is 0.066 +/- 0.003. The spectrum of 2010lp shows features resembling peculiar 2005hk-like type-Ia supernovae, shortly after maximum light. In particular, the authors find a relatively good match with the spectrum of SN 2007on at 2-4 days after maximum. After correcting for the recession velocity of the host galaxy, NGC 1137 (3042 km/s from the RC3 galaxy catalogue), they measure a blueshift from the Si II (rest 635.5 nm) profile of 11600 km/s. The object reported on CBET 2611 is a young, normal type-Ia supernova, and thus designated here as SN 2010lq. The best-fitted SNID template is that of SN 2000E at -6 days. After correcting for the recession velocity of the host galaxy, ESO 495-16 (7924 km/s; Yamada et al. 1994, MNRAS, 270, 93), the authors measure a blueshift for the Si II (rest 635.5 nm) profile of 10200 km/s.
