SUPERNOVAE 2010ig AND 2010io
     D. Milisavljevic and R. Fesen, Dartmouth College, report on low-dispersion
spectra (range 440-770 nm) taken on Oct. 10 UT with the 2.4-m Hiltner telescope
(+ Mark III) at MDM Observatory.  The object near UGC 4543 discovered by
Duszanowicz (cf. CBET 2481), here designated 2010io, is likely a type-Ic
supernova; comparison with a library of supernova spectra using the
"Supernova Identification" tool (SNID; Blondin and Tonry 2007, ApJ., 666, 1024)
provides reasonable matches with type-Ic events around three months post-
maximum light.  A spectrum of SN 2010ig (cf. CBET 2470) resembles that of the
type-Ib supernova 1999ex around maximum light.
