SUPERNOVA 2014ay IN UGC 11037
     T. W.-S. Holoien and B. J. Shappee, Ohio State University; J. Brimacombe,
Cairns, Australia; K. Z. Stanek, C. S. Kochanek, J. Jencson, U. Basu, A. B.
Davis, and J. F. Beacom, Ohio State University; J. L. Prieto, Princeton
University; D. Szczygiel and G. Pojmanski, Warsaw University Observatory; and
D. Bersier, Liverpool John Moores University, report the discovery of a new
transient source (V about 16.7) at the center of UGC 11037 on images taken on
May 4.47 UT on CCD images taken with the quadruple 14-cm "Brutus" telescope at
Haleakala in the course of the All-Sky Automated Survey for SuperNovae
(ASASSN).  The new object is located at R.A. = 17h55m05s.434, Decl. =
+18d15'26".45 (equinox 2000.0).  Nothing is visible at this position on ASASSN
images taken on Apr. 25.53 and earlier (limiting V-band mag 17.0).  The new
object is given the designation SN 2014ay based on the spectroscopy reported
below.  UGC 11037 does not appear to be a known active-galactic-nucleus host.

     P. Ochner, S. Benetti, L. Tomasella, A. Pastorello, N. Elias-Rosa, E.
Cappellaro, and M. Turatto, Osservatorio Astronomico di Padova, Istituto
Nazionale di Astrofisica, report that an optical spectrogram (range 335-785
nm; resolution 0.9 nm), obtained on May 8.06 UT with the Asiago 1.22-m Galileo
Telescope (+ Boller & Chivens spectrograph), shows that 2014ay is a type-II
supernova.  Assuming a recessional velocity of 3127 km/s for the host galaxy
(Schneider et al. 1990, Ap.J. Suppl. 72, 245; via NED), a good match is found
with type-II supernovae at a few days after explosion.  The Asiago
classification spectra are posted at website URL http://sngroup.oapd.inaf.it.
Classification was made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383)
and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
