A. Harutyunyan, S. Benetti, and F. Sabbadin, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, report that a spectrum of 2008eg, obtained on July 21.19 UT with the 3.5-m TNG reflector (+ DOLORES; range 340-775 nm, resolution 1.1 nm), shows it to be a type-Ia supernova around maximum light. The best fit to this spectrum found by GELATO (Harutyunyan et al. 2008, http://lanl.arxiv.org/abs/0804.1939) is with a spectrum of SN 1996X (cf. Salvo et al. 2001, MNRAS 321, 254) at two days before maximum light. Adopting a recession velocity of 10090 km/s for the host galaxy (Giovanelli and Haynes 1993, A.J. 105, 1271; via NED), the expansion velocity deduced from the Si II 635.5-nm absorption is about 10700 km/s.
