SUPERNOVA 2012dl IN ESO 459-6 = PSN J19120821-3207370
     M. Fraser, R. Kotak, D. Wright, K. Smith, S. J. Smartt, L. Magill, and
M. McCrum, Queens University, Belfast, report that an optical spectrogram
of PSN J19120821-3207370 = SN 2012dl (cf. CBET 3170) was obtained by J.
Jensen-Hansen with the Nordic Optical Telescope (+ ALFOSC + Grism#4; coverage
320-910 nm; resolution about 1.4 nm) on July 7.  Using the GELATO code
(Harutyunyan et al. 2008, A.Ap. 488, 383), the spectrum of 2012?? appears to
match a range of type-Ia supernovae between 30 and 40 days from maximum light
at the redshift of ESO 459-6.  The absolute magnitude of the supernova at the
discovery epoch (R = -16.1) reported by J. Brimacombe suggests that 2012??
was either discovered before maximum light or that the supernova is reddened.
Unfortunately, the signal-to-noise of the spectrum is too low to identify any
Na D absorption.
