Supernova 2002ce:

• Discovered: April 10, 2002, by R. Arbour, South Wonston, Hants., England.
• Magnitude 16.5 at discovery, and 17.5 in the Kopernik image.
• Type II
• The expansion velocity is 5,300 km/s.

Galaxies NGC 2604 and MCG 5-20-23 in the Constellation of Cancer have nearly the same red shift. NGC 2604 is a Barred Spiral Galaxy with two spiral arms and a separate condensation in the disk. MCG 5-20-23 is a nearby Irregular Galaxy that is much like the Milky Way's Magellanic Clouds.

Using the red shift data from the “NASA Extra-galactic Data Base(NED)”, (and a Hubble Constant of 62 Km per sec., per Megaparsec), one can calculate a rough distance estimate for this pair of galaxies, and SN 2002ce, of about 110 million light years.

NGC 2604 Magnitude: 13.0 Constellation: Cancer RA: 08h 33m 22.9s Dec: +29° 32' 17" Epoch 2000 Size (mins): 2.1' x 2.1' Classification: SB(rs)cd        Barred Spiral Galaxy, Mixed inner-ring, S-shaped Dreyer description in the NGC:        "Very faint, pretty large, round, little brighter middle, resolvable, but mottled, double star nearby."

MCG 5-20-23 Magnitude: 15.4 RA: 08h 33m 35.5s Dec: +29° 29' 57" Epoch 2000 Size (mins): 0.8' x 0.4' Classification: Im        Irregular Galaxy, Magellanic type
