SUPERNOVA 2010ab IN PGC 27294
     M. Fraser, S. Valenti, and S. Smartt, Queens University, Belfast; and
M. Sullivan and I. Hook, Department of Astrophysics, Oxford University,
report that a spectrum of 2010ab (cf. CBET 2172) was obtained at the William
Herschel Telescope (+ ISIS; range 320-1000nm) on Feb. 22.10 UT.  The spectrum
shows a blue continuum with Balmer lines typical of a young type-II supernova.
Cross-correlation of the observed spectra with a library of supernova spectra
has been performed with the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488,
383, https://gelato.tng.iac.es/login.cgi).  The spectrum gives a good match
to those of several type-II supernovae close to maximum light.  A redshift of
z = 0.046 was estimated from the narrow Balmer lines of the host galaxy.
Taking the magnitude of 17.8 reported on CBET 2172, SN 2010ab has an absolute
mangitude of -18.6, which is consistent with the magnitude of bright type-II
supernovae.
