SUPERNOVA 2014aq
     [Editor's note:  this replaces the text on CBET 3858 (discovery data).]
     E. S. Walker, E. Hadjiyska, D. Rabinowitz, C. Baltay, N. Ellman, and R.
McKinnon, Yale University; U. Feindt, Universitaet Bonn; and P. Nugent,
Lawrwnce Berkeley National Laboratory and University of California at
Berkeley, report the discovery of an apparent supernova (mag 17.7) in a
wide-band CCD image (limiting mag 19.5 in the QUEST g' + r' filter) taken
with the 1-m Schmidt telescope at the European Southern Observatory, La
Silla, on Apr. 14.3 UT in the course of the La Silla-Quest Survey (LSQ;
Baltay et al. 2013, PASP 125, 683).  The new object is located at R.A. =
11h12m34s.72, Decl. = +12o04'24".8 (equinox 2000.0), which is 2".5 west and
4".3 north of the center of the galaxy SDSS J111234.89+120420.4.  Nothing is
visible at this position on LSQ images taken on Apr. 4 (limiting mag 20.5).

     L. Galbany and S. Gonzalez-Gaitan, Millennium Institute of Astrophysics,
Universidad de Chile; K. Muzic and V. D. Ivanov, European Southern
Observatory (ESO); E. S. Walker, E. Hadjiyska, D. Rabinowitz, C. Baltay, N.
Ellman, and R. McKinnon, Yale University; U. Feindt, Universitaet Bonn; and
P. Nugent, Lawrence Berkeley National Laboratory and University of California
at Berkeley, report that an optical spectrogram of 2014aq, obtained on Apr.
17.21 UT with the ESO New Technology Telescope at La Silla (+ EFOSC2 in
long-slit mode with 1" slit and grisms 3 and 5, for wavelength ranges 305-610
nm at resolution 1.26 nm and 520-935 nm at resolution 1.66 nm, respectively),
shows it to be a type-Ia supernova.  A comparison of the observed spectrum
with a library of supernova spectra using SNID (Blondin and Tonry 2007, Ap.J.
666, 1024) suggests that 2014aq was then days before maximum light, with SN
2002bo being the best-match template.
