2010CBET.2298....1S

D. K. Sahu, G. C. Anupama, and S. Arora, Indian Institute of Astrophysics, Bangalore, report that a low-resolution spectrum (range 350-930 nm) of 2010dl (cf. CBET 2296), obtained on May 30.87 UT with the Indian Astronomical Observatory's 2-m Himalayan Chandra Telescope (+ HFOSC), shows it to be a normal type-Ia supernova, a few days after maximum light. Using the SNID code of Blondin and Tonry (2007, Ap.J. 666, 1024), the spectrum of 2010dl is found to be similar to that of SN 1998aq at about six days after maximum light. After correcting for the recession velocity of the host galaxy, IC 1391 (9004 km/s, via NED; Jones et al. 2004, MNRAS 355, 747; Jones et al. 2009, MNRAS 399, 683), the velocity of the Si II 635.5-nm absorption is measured to be 10500 km/s.
