SUPERNOVA 2002hf IN MCG -05-3-20
Further to IAUC 8002, D. Hutchings and W. D. Li report the
LOTOSS discovery of an apparent supernova (mag about 16.5) on
unfiltered KAIT images taken on Oct. 29.3 and 30.3 UT. SN 2002hf
is located at R.A. = 0h57m47s.74, Decl. = -27o30'21".5 (equinox
2000.0), which is 10".5 east and 15".7 south of the nucleus of MCG
-05-3-20. KAIT images taken on Oct. 2.3 (limiting mag about 18.5)
and 22.3 (limiting mag about 17) showed nothing at this position.
SUPERNOVA 2002hg IN NGC 3306
T. Boles, Coddenham, England, reports the discovery of an
apparent supernova (mag 17.0) on an unfiltered CCD image taken on
Oct. 28.219 UT with a 0.35-m reflector in the course of the U.K.
Nova/Supernova Patrol. The new object is located at R.A. =
10h37m10s.60, Decl. = +12o39'13".2, which is approximately 6".3
east and 3".8 north of the center of NGC 3306. M. Schwartz,
Cottage Grove, OR, confirmed the new object with the 0.82-m Tenagra
telescope on Oct. 30.54 in morning twilight. Boles measured R =
16.7 and position end figures 10s.60 and 12".8 from Schwartz'
image. SN 2002hg is not present on Boles' images from Jan. 16
(limiting mag 18.5), Mar. 2, or Apr. 11, and it is not present on
Palomar Sky Survey red (1993) and blue (1994) plates or on a
Quick-V survey plate (1985).
SUPERNOVA 2002he IN UGC 4322
T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that a spectrum (range 370-750 nm)
of SN 2002he (cf. IAUC 8002), obtained by I. Ginsburg on Oct. 30.47
UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST
spectrograph), shows it to be a possibly peculiar type-Ia supernova
near maximum. Some titanium features appear stronger than normal,
indicating that this may be a subluminous event. The spectrum is
similar to that of SN 2000dk at 4 days before maximum. Adopting
the NED recession velocity of 7364 km/s for the host galaxy, the
supernova expansion velocity is about 13900 km/s for Si II (rest
635.5 nm).
V4744 SAGITTARII
T. Kato, Kyoto University, reports that nothing was visible at
the location of V4744 Sgr on T-Max 400 exposures taken by H.
Nishimura, Kakegawa, Shizuoka, Japan, on Oct. 25.40 UT (limiting
mag 10.5).
