Schwartz, Cottage Grove, OR; and W. D. Li, University of California at Berkeley, on behalf of LOTOSS, report the discovery of an apparent supernova on an unfiltered image taken with the 0.5-m Tenagra III automated telescope on Nov. 20.5 UT (mag about 16.8). SN 2001gb is confirmed at mag about 18.2 on an earlier image taken by the Katzman Automatic Imaging Telescope (KAIT) on Nov. 11.5. The new object is located at: R.A. = 9h59m00s.96, Decl. = +17o49'12".4 (2000), which is about 10".8 east and 11".1 north of the nucleus of IC 582. IAUC 7758 (extract) SUPERNOVA 2001gc IN UGC 3375 M. Schwartz, Cottage Grove, OR; and W. D. Li, University of California at Berkeley, on behalf of LOTOSS, report the discovery of an apparent supernova on an unfiltered image taken with the 0.5-m Tenagra III automated telescope on Nov. 21.4 UT (mag about 16.2). SN 2001gc is confirmed at mag about 16.8 on an earlier image taken by the Katzman Automatic Imaging Telescope under poor conditions on Nov. 19.5. The new object is located at: R.A. = 5h55m26s.14, Decl. = +51o54'34".2 (equinox 2000.0), which is 7".3 east and 4".3 south of the nucleus of UGC 3375. IAUC 7759 (extract) SUPERNOVA 2001fv IN NGC 3512 This object, discovered by Mark Armstrong and announced on TA E- Circular 1708, has been spectroscopically confirmed as follows: T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard- Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2001fv, obtained by P. Berlind on Nov. 14.52 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph), shows it to be a type-II supernova well past maximum light. The spectrum shows a continuum with well-defined P-Cyg lines of hydrogen, sodium, and iron, consistent with the plateau phase of a normal type-II supernova. IAUC 7756 (extract) Guy M Hurst
