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.
