SUPERNOVA 2014ax IN UGC 10318
Further to the announcement of a suspected supernova on TA E-Circular 3000,
D. Milisavljevic et. al., Harvard-Smithsonian Center for Astrophysics; and
E. O. Martin, MMT Observatory, report that a low-dispersion spectrogram
(range 335-855 nm), obtained on May 6.4 UT with the 6.5-m MMT telescope (+
Blue Channel), shows PSN J16161816+6406063 = SN 2014ax to be a type-II
supernova.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) shows a reasonable match with the type-IIP event 1999gi at five days
before maximum light.

The spectrum exhibits features that are consistent with a young age,
including a blue continuum and shallow P-Cyg absorptions associated with H
Balmer lines.  After correcting for the redshift z = 0.0324 of the host
galaxy (UGC 10318), as measured from coincident narrow H_alpha emission, the
minimum of the broad H_beta line absorption is blueshifted approximately
8800 km/s.

The designation Supernova 2014ax is now assigned by the Central Bureau.
Congratulations to Tom on his 155th supernova discovery.
