2003IAUC.8158....1M

Further to IAUC 8156, M. Moore, M. Papenkova, and W. Li report the LOTOSS discovery of an apparent supernova (mag about 18.5) on unfiltered KAIT images on June 27.4 and 28.4 UT. SN 2003gg is located at R.A. = 20h28m10s.68, Decl. = -18o17'32".4 (equinox 2000.0), which is 5".8 west and 2".9 south of the nucleus of IC 1321. A KAIT image taken on 2002 July 9.4 showed nothing at this position (limiting mag about 19.0). A. V. Filippenko and R. Chornock, University of California, Berkeley, report that inspection of CCD spectra (range 320-900 nm) obtained on June 29 with the Keck-I telescope (+ LRIS) reveals that SN 2003gg is of type II, probably 1-2 months after the explosion. Hydrogen Balmer lines, Na D, and Fe II lines exhibit well-developed P-Cyg profiles.
