From IAU Bulletin 7122 (3/6/99):
Spectra obtained by M. M. Phillips and W. Kunkel of Las Campanas Observatory...... shows this to be a peculiar..... type-Ia event that has been caught near, or a few days before, maximum.
The Kopernik image above is nearly 4 months after discovery and the supernova is around 16th magnitude.
Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.
Spiral Galaxy NGC 6063:
Although NGC 6063 is classified as 'Spiral, uncertain', more recent observations seem to confirm that it is a spiral galaxy and perhaps has a short bar.
Dreyer's description from the New General Catalog(NGC): Faint, pretty large, round, very little brighter middle.
Based on the published red shift, a rough distance estimate for NGC 6063 and supernova 1999ac is: 150 million light years, with the galaxy being 74,000 light years in diameter.
