SUPERNOVA 1999gi IN
NGC 3184
S. Nakano, Sumoto, Japan, reports the discovery by Reiki Kushida, Yatsugatake
South Base Observatory, of a supernova (mag
14.5) on unfiltered CCD frames taken on Dec. 9.82 UT with a 0.40-m reflector.
Previous frames that she took between 1994 and 1999 May
6 show nothing at this location (limiting mag 18), and nothing appears at the
location of the new object on a Digital Sky Survey
image. Position measured by Y. Kushida for
SN 1999gi: R.A.
= 10h18m16s.66, Decl. = +41°26'28".2 (equinox 2000.0), which is 3".5
west and 60".5 north
of the center of
NGC 3184. W. Li, University of California at Berkeley, reports that a KAIT
image of NGC 3184
taken on Dec. 2.5 shows nothing at the position of SN 1999gi (limiting mag
19.0).
S. Jha, P. Garnavich, P. Challis, and R. Kirshner, Harvard- Smithsonian Center
for Astrophysics, report that a spectrum of SN
1999gi, taken by A. Mahdavi and Jha with the F. L. Whipple Observatory (FLWO)
1.5-m telescope (+ FAST spectrograph) on Dec.
10.42 UT, reveals it to be a type-II supernova at an early epoch.
