SUPERNOVA 2000C IN NGC 2415
Independent discoveries of a new apparent
supernova in NGC
2415 have been made by Steven Foulkes, Ashperton Village, England,
on Jan. 8.789 UT (communicated via G. Hurst) and by Marco Migliardi,
Cortina, Italy, on Jan. 12.95 (via M. Villi). Foulkes' discovery
was made on an unfiltered CCD image taken with a 0.26-m reflector
in the course of the U.K. Nova/Supernova Patrol. Migliardi
obtained the following position for SN 2000C from his discovery
image: R.A. = 7h36m57s.09, Decl. = +35o14'38".8 (equinox 2000.0),
which is 8".3 east and 7".4 north of the nucleus of NGC 2415.
W.
Li, University of California at Berkeley, reports that a
prediscovery image (limiting mag 19.5-20.0) of SN 2000C appears on
a CCD frame taken on Jan. 8.3 with the Katzman Automatic Imaging
Telescope (KAIT) at Lick Observatory, from whence he provides the
following position end figures: 56s.99, 37".2. Li adds
that
although SN 2000C is very close to the location of SN 1998Y (cf.
IAUC 6850), comparison with KAIT images of SN 1998Y shows that the
new object is slightly north and east of SN 1998Y (see
http://astron.berkeley.edu/~bait/2000/ngc2415.html); he also notes
that SN 1998Y faded from view on KAIT images in Oct. 1998.
Estimated magnitudes for SN 2000C: 1999 Dec. 15.995, [17:
(Foulkes); 26, [19.0 (Li); 30, [18.5 (Li); 2000 Jan. 4, 19.5-20.0
(Li; only hint of new object); 8.3, 18.0: (Li); 8.789, 15.6:
(Foulkes); 12.95, 15.5 (Migliardi).
