SUPERNOVA 2013cd IN UGC 4294 = PSN J08164900+6029285
     D. Rich, T. Harvey, J. Rosebush, and C. Sawyer report their discovery of
an apparent supernova (mag about 17.0) on unfiltered CCD frames (limiting mag
19.4) taken with a 0.41-m reflector on Apr. 28.061 UT in Hampden, ME, U.S.A,
in the course of the Eagle Hill Supernova Search Project.  The new object is
located at R.A.= 8h16m49s.0, Decl. = +60o29'28".5 (equinox 2000.0) which is
about 2".3 west and 6".4 south of the center of UGC 4294.  Nothing is visible
at this position on Palomar Digital Sky Survey images from 1989 Dec. 21
(limiting red mag about 20.3) and 1990 Jan. 1 (limiting blue mag about 21.0).
The variable was designated PSN J08164900+6029285 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2013cd based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2013cd:  Mar. 10.050, [19.2 (Rich); Apr. 29.034, 16.8 (Rich et al.; limiting
mag 19.4); Apr. 29.331, 16.7 (Joseph Brimacombe, Cairns, Australia; remotely

Mexico Skies observatory near Mayhill, NM, U.S.A.; position end figures

     P. Ochner, A. Pastorello, L. Tomasella, S. Benetti, E. Cappellaro, and M.
Turatto, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica,
report that an optical spectrogram (range 340-790 nm; resolution 0.9 nm),
obtained on May 5.02 UT with the Asiago 1.22-m Galileo Telescope (+ Boller &
Chivens spectrograph), shows that PSN J08164900+6029285 = SN 2013cd is a
reddened type-I supernova (most likely a type-Ia event).  Adopting a
recessional velocity of 11716 km/s for the host galaxy (Huchra et al. 2012,
Ap.J. Suppl. 199, 26), an expansion velocity of about 11700 km/s is measured
from the minimum of the Si II 635-nm line.  The Asiago classification spectra
are posted at website URL http://graspa.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).
