Further to IAUC 8230, M. Moore and W. Li report the LOSS/KAIT discovery, on images taken on Oct. 22.4 and 23.4 UT, of an apparent supernova (mag about 17.1) located at R.A. = 2h12m11s.81, Decl. = +44o34'20".8 (equinox 2000.0), which is 5".6 west and 13".7 north of the nucleus of NGC 846. A KAIT image taken on Oct. 7.4 showed nothing at this position (limiting mag about 19.0). A. V. Filippenko, R. Chornock, and S. Jha, University of California, Berkeley, report that inspection of CCD spectra (range 320-1000 nm), obtained on Oct. 23 with the Shane 3-m telescope at Lick Observatory, reveals that SN 2003ja is a supernova, probably of type II shortly after the explosion. The continuum is very blue and nearly featureless.
