POSSIBLE NOVA IN SAGITTARIUS
S. Nakano, Sumoto, Japan, reports the discovery of a possible
nova (mag 10.5) by Yukio Sakurai, Otsuka-cho, Mito, on two Fuji
Color Super G400 films taken with a 300-mm f/2.8 lens on Feb. 4.863
UT. A prediscovery film by Sakurai on Jan. 25.863 shows the star
at mag 11.5. It was not present on his films taken between 1991
and 2000 Jan. 20 (limiting mag 10.8 on Jan. 20). A CCD frame taken
with a 0.40-m f/6 reflector on Feb. 6.812 by Y. and R. Kushida,
Yatsugatake South Base Observatory, shows the star at mag 10.4 and
yields the following position: R.A. = 17h55m09s.84, Decl. =
-19o46'01".0 (equinox 2000.0). J. Mattei, AAVSO, reports that no
object was found by K. Malatesta, AAVSO, at the position of the new
star on the Digital Sky Survey (SERC-V Equatorial Extension, epoch
1987.336).
SUPERNOVA 2000I IN NGC 2958
T. Puckett, Mountain Town, GA; and D. George, Ottawa, ON,
report the discovery of an apparent supernova (mag 18.6) on an
unfiltered CCD frame (limiting mag 20.3) taken with the Puckett
Observatory 0.60-m automated supernova patrol telescope on Feb.
4.17 UT. SN 2000I is located at R.A. = 9h40m41s.54, Decl. =
+11o53'08".5 (equinox 2000.0), which is 1".8 west and 10".2 south
of the center of NGC 2958. The new object was also present on an
unfiltered CCD frame taken on Feb. 6.34, but it does not appear on
Palomar Sky Survey images taken on 1995 Mar. 29 (limiting mag about
21.0) and on 1954 Feb. 26 (limiting mag about 20.1). A. Rest and
K. Krisciunas, University of Washington, report an observation of
SN 2000I on Feb. 10.32 with the Apache Point Observatory 3.5-m
telescope, yielding V = 17.85 +/- 0.06, B-V = +0.84 +/- 0.04.
SUPERNOVA 2000J IN UGC 8510
Puckett and George also report the discovery of an apparent
supernova (mag 19.5) in UGC 8510, found on an unfiltered CCD frame
(limiting mag 20.5) taken as above on Feb. 4.37 UT. SN 2000J is
located at R.A. = 13h31m16s.24, Decl. = +29o22'32".3 (equinox
2000.0), which is 16".9 west and 28".3 north of the center of UGC
8510. The new object was also present on an unfiltered CCD frame
taken on Feb. 6.24, but it does not appear on Palomar Sky Survey
images taken on 1989 Mar. 5 (limiting mag about 21.1) and on 1950
June 5 (limiting mag about 20.0). Rest and Krisciunas report that
an observation of SN 2000J made (as above) on Feb. 10.30 yields V
= 18.52 +/- 0.10, B-V = +1.14 +/- 0.08.
