SN 2007gn is located at R.A. = 3h16m31s.37, Decl. = +15o27'40".7 (equinox 2000.0). A spectrum (range 320-1000 nm), obtained on Aug. 8.6 with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows that the new object is a type-Ia supernova, three weeks after maximum, at an approximate redshift of z = 0.036.
