NGC 524 & Supernova 2000cx
An 8 minute exposure with an ST-6
CCD camera thru Kopernik's 20-inch F/8.1 Ritchey Chretien Cassegrain telescope.
The field of view is about 5x6.5 arc minutes, with North at the top. Time:
6:50 UT, August 5th, 2000.
Discovered: July 17th, 2000,
by Lick Observatory Supernova Search.
- Magnitude 14.5 at discovery
- Type Ia-pec
- From IAU Circular 7463:
"....a CCD spectrum ..... obtained on July 23 UT with the Nickel 1-m
reflector at Lick Observatory reveals that the object is a peculiar type-Ia
supernova, strongly resembling the over-luminous SN 1991T a few days before
maximum brightness.....The object is in the outskirts of the host galaxy,
which has a Hubble type of S0 (i.e. Lenticular); this is the first
time that a SN 1991T-like type-Ia object has been seen in such an early-type
galaxy, in a region devoid of obvious dust and massive stars. Frequent
observations at all wavelengths are encouraged. "

of what these objects are.
Lenticular Galaxy NGC 524:
This face-on lenticular galaxy is
in the constellation of Pisces. A rough distance estimate for this galaxy
is 130 million light years, and at that distance, the diameter would be
105,000 light years.
G. and A. DE VAUCOULEURS, "REFERENCE CATALOGUE OF BRIGHT GALAXIES":
"Extremely bright nucleus in
a very bright, inner smooth part: 0.9 arc min x 0.8 arc min. Very weak,
narrow rings, or arcs, outline lens...... In a group of 3 lenticulars and
Sa spirals + others."
