SUPERNOVAE IMAGES TAKEN AT NIGHTWATCH
Above: Supernova 2007gi in galaxy NGC 4036. Taken with ST6 C8 camera.
Discovered by Koichi Itagaki on 2007/07/31.49 and was located 23" W and
11" S of galaxy's center. Classifies as a type 1A Super Nova with
a z=0.004820 and at a distance of 20.4 Mpc. NG 4036 is located in
the constellation Ursa Major and had a magnitude of 10.6.
Above: Supernova 2008R in the galaxy NGC 1200.
Taken with ST6-C8 camera. SN 2008r ws discovered by Koichi Itagaki
on 2008/01/27.45. It was located 12" W and 09" S of the galaxy
nucleus and classified as type 1a. NGC 1200 is located in the
constellation Eridanus and has a magnitude of 13.0.
Above: Supernova SN2008AX in the galaxy NGC 4490.
Shown here at magnitude 13.9 and imaged with the ST6-C8 camera on 09
April 2008. This type Ib (CfA spectrum) super nova was discovered
04 March 2008 by Koichi Itagaki. The RA offset is 53.1 arc sec and the
DC offset is -25.8 arc sec, or 53.1" E and 25.8" S. NGC 4490 is
interacting with the galaxy NGC 4485 to it's North or just below this
very nice peculiar galaxy. A great target, and should be on any
amateur's list of objects to view. Certainly, a must on the way to
M51. Also to be found on many charts is the designation Leda 89542
associated with the pair, which is a surrounding faint halo. North
is down. The galaxy NGC 4490, a type G and also known as Arp 269, is
some times referred to as the Cocoon Galaxy. A faint indication of
the perfuse HII regions are evident in the lower edge of 4490.
