Maza, University of Chile; and M. Hamuy, University of Arizona, report the discovery by R. Antezana, on a 30-min unfiltered T-Max 400 film taken by L. Gonzalez on Apr. 28.18 UT with the University of Chile's Maksutov telescope, of an apparent supernova (mpv 16.0) located at R.A. = 13h35m22s.98, Decl. = -34o09'37".0 (2000), which is 0".6 east and 4".7 north of the nucleus of ESO 383-32. IAUC 7409 (extract) SUPERNOVA 2000cb IN IC 1158 M. Papenkova and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search, report the discovery, on an unfiltered image taken on Apr. 27.4 UT with the 0.8-m Katzman Automatic Imaging Telescope (KAIT), of an apparent supernova (mag about 18.0) located at R.A. = 16h01m32s.15, Decl. = +1 42'23".0 (2000), which is 29".5 west and 4".2 south of the nucleus of IC 1158. IAUC 7410 (extract) CI AQUILAE Bill Liller, Vina del Mar, Chile, reports that a prediscovery hypersensitized Technical Pan film, taken on Apr. 28.260 UT with an 85-mm f/2.0 camera lens and orange filter, clearly shows CI Aql at mag 9.8. He adds: "CCD spectroscopy with an objective prism shows H-alpha with an intensity 4.3 times that of the neighboring continuum. The [O I] lines at 630 and 636 nm are also strong, and there is evidence of He II at 587 nm. H-beta is present but weak, probably owing to interstellar reddening. CCD imaging with a 0.20-m Schmidt camera and a broadband-V filter (that includes the strong H-alpha emission) yields the following magnitudes: Apr. 30.360, 8.87; 30.398, 8.95." IAUC 7411 (extract) SUPERNOVA 2000cc IN CGCG 140-014 Y. Sato and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search, report the discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparent supernova on unfiltered images taken on Apr. 30.5 (limiting mag about 19.0) and May 1.5 UT (limiting mag about 20.5), both showing the new star at mag about 18.5. SN 2000cc was also present on an unfiltered image taken on Apr. 26.5 at about the same brightness, and the new object is located at: R.A. = 17h23m14s.34, Decl. = +23o40'18".7 (2000), which is 5".9 east and 9".1 south of the nucleus of CGCG 140-014. IAUC 7413 (extract) VARIABLE STAR IN FIELD OF NGC 3432 (=Q2000/261) M. Papenkova and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search, report the discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of a variable star (thought not to be a supernova) in the field of NGC 3432. The new object was discovered and confirmed on unfiltered images taken on May 3.2 (mag about 17.4) and 4.2 UT (mag about 18.2), respectively. The new object is located at: R.A. = 10h52m41s.40, Decl. = +36o40'08".5 (2000), which is about 123" east and 180" north of the diffuse nucleus of NGC 3432 and superimposed on an H II region of the galaxy. IAUC 7415 (extract) Editor: Interest is being shown in this object by the GRB team. Please send urgently any present or past images to the editor. Guy M Hurst
