We obtained SALT (+RSS) spectroscopy of PS16fbb (= Gaia16bvg = SN
2016ick) on 2016 Nov 25.9 UT, covering the wavelength range 340-920
nm. Emission and absorption lines from the anonymous host galaxy give
a redshift z = 0.0525. Cross-correlation of the supernova spectrum
with a template library using SNID (Blondin & Tonry 2007, ApJ, 666,
1024) shows PS16fbb is a type-Ia supernova near maximum light. A good
SNID match is obtained with SN 2005cf at -2 days. The expansion
velocity for PS16fbb, measured to the trough of the Si II (rest 635.5
nm) line, is 10,200 km/s.
Our spectrum is posted on the Transient Name
Server SN 2016ick page.
PS16fbb was discovered as part of the Pan-STARRS Survey for
Transients (Huber et al. 2015, ATel #7153). Information on all PSST
