Nakano, Sumoto, Japan, reports the discovery of a possiblenova (mag 10.5) by Yukio Sakurai, Otsuka-cho, Mito, on two FujiColor Super G400 films taken with a 300-mm f/2.8 lens on Feb. 4.863UT. A prediscovery film by Sakurai on Jan. 25.863 shows the starat mag 11.5. It was not present on his films taken between 1991and 2000 Jan. 20 (limiting mag 10.8 on Jan. 20). A CCD frame takenwith 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 andyields the following position: R.A. = 17h55m09s.84, Decl. =-19o46'01".0 (equinox 2000.0). J. Mattei, AAVSO, reports that noobject was found by K. Malatesta, AAVSO, at the position of the newstar on the Digital Sky Survey (SERC-V Equatorial Extension, epoch1987.336).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 anunfiltered CCD frame (limiting mag 20.3) taken with the PuckettObservatory 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 southof the center of NGC 2958. The new object was also present on anunfiltered CCD frame taken on Feb. 6.34, but it does not appear onPalomar Sky Survey images taken on 1995 Mar. 29 (limiting mag about21.0) and on 1954 Feb. 26 (limiting mag about 20.1). A. Rest andK. Krisciunas, University of Washington, report an observation ofSN 2000I on Feb. 10.32 with the Apache Point Observatory 3.5-mtelescope, 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 apparentsupernova (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 islocated at R.A. = 13h31m16s.24, Decl. = +29o22'32".3 (equinox2000.0), which is 16".9 west and 28".3 north of the center of UGC8510. The new object was also present on an unfiltered CCD frametaken on Feb. 6.24, but it does not appear on Palomar Sky Surveyimages taken on 1989 Mar. 5 (limiting mag about 21.1) and on 1950June 5 (limiting mag about 20.0). Rest and Krisciunas report thatan observation of SN 2000J made (as above) on Feb. 10.30 yields V= 18.52 +/- 0.10, B-V = +1.14 +/- 0.08. (C) Copyright 2000 CBAT2000 February 10 (7362) Daniel W. E.
