SUPERNOVA 2014db IN UGC 2988 = PSN J04133846+2528462
     Further to CBET 3942, C. Casper, W. Zheng, and A. V. Filippenko,
University of California at Berkeley, report the LOSS discovery of a possible
supernova in UGC 2988 on unfiltered KAIT images:

 SN       2014 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2014db   Aug. 27.52   4 13 38.46  +25 28 46.2   17.1    4".3 W, 12".2 S

A finding chart was posted by the discoverers at the following website URL:
http://astro.berkeley.edu/~zwk/findingchart/PSN_J04133846+25284620.jpg.  The
variable was designated PSN J04133846+2528462 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014db based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014db:  Aug. 28.99 UT, 17.6 (G. Masi, P. Catalano, and P. Schmeer; remotely
using a 43-cm telescope at Ceccano, Italy; position end figures 38s.48,
46".0); 29.51, 17.1 (KAIT).

     W. Zheng, K. I. Clubb, and A. V. Filippenko, University of California,
Berkeley, report that inspection of a CCD spectrogram (range 350-1000 nm),
obtained on Sept. 3.480 UT with the Shane 3-m reflector (+ Kast spectrograph)
at Lick Observatory, shows that PSN J04133846+2528462 = SN 2014db is a
type-IIP supernova.  Cross-correlation with a library of supernova spectra
using the "SuperNova Identification" code (SNID; Blondin and Tonry 2007, Ap.J.
666, 1024) indicates a similarity with many type-IIP supernovae about a month
after explosion.
