The Nearby Supernova Factory reports that a spectrum (range 340-1000 nm) of the SN in UGC 8539 (Tim Puckett, private communication), obtained April 29.5 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows it to be an early Type II at the redshift of the host galaxy. Present in this blue spectrum are the Hydrogen features H-alpha through H-delta as well as He I 587.6 nm.
