FLOYDS Classification of ASASSN-14dq as a Young Type II SN
I. Arcavi, S. Valenti, D. A. Howell (LCOGT) and D. Sand (Texas Tech)
We obtained a spectrum of ASASSN-14dq (ATel #6301) on 2014 July 9.5 (UT) with the robotic FLOYDS instrument mounted on the Faulkes Telescope North. The spectrum displays a blue continuum with broad hydrogen p-cygni features having absorption minima at ~10000 km/s. Using Superfit (Howell et al. 2005, ApJ, 634, 1190), we find a good match to an early spectrum of the Type IIb SN 1993J at the redshift of the host galaxy (z=0.01), though it is probably too early to determine the precise subtype of ASASSN-14dq.
