SUPERNOVA 2010dd IN UGC 10594
     D. Young, P. R. Dunstall, S. Valenti, and S. Smartt, Queens University;
and M. Sullivan and I. Hook, Astrophysics Department, Oxford University,
report that a spectrum of 2010dd (cf. CBET 2294) was obtained at the William
Herschel Telescope (+ ISIS; range 320-1000 nm) on June 8.98 UT, showing
2010dd to be a type-Ia supernova at two months after explosion.  Cross-
correlation of the observed spectrum with a library of supernova spectra has
been performed with the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488,
383, available at website URL https://gelato.tng.iac.es/login.cgi).  The
spectrum of 2010dd is similar to that of SN 2000fa (IAUC 7533) at 40 days
past maximum at a redshift of z = 0.03.
