M. Hurst, Basingstoke, England, reports the discovery of anapparent supernova (mag 16.8) by M. Armstrong, Rolvenden, on a CCDexposure obtained on Nov. 24.167 UT with a 0.35-m telescope in thecourse of the U.K. Nova/Supernova Patrol.  SN 2000ez is located atR.A. = 11h57m45s.75, Decl. = +32o17'49".1 (equinox 2000.0), whichis 22".5 east and 12" north of the center of NGC 3995.  The newobject was confirmed on images taken by M. Schwartz (0.52-mtelescope; mag 16.9) on Nov. 28.846, by P. Garnavich (VaticanAdvanced Technology Telescope; R = 17.5) on Nov. 29.5, and byArmstrong on Nov. 30.731.  Garnavich adds that SN 2000ez appearsred and may be extinguished by dust in the host galaxy.  SN 2000ezdoes not appear on second Palomar Sky Survey images taken on 1991Apr. 3 (red plate; limiting mag 20.8) and on 1996 Mar. 17 (blueplate; limiting mag 22.5), or on CCD images obtained by T. Boles(1999 Dec. 5) and by the Lick Observatory Supernova Search (1999May 8).SUPERNOVA 2000fa IN UGC 3770     A. Friedman and W. D. Li, University of California at Berkeley,on behalf of LOTOSS (cf.IAUC 7514), report the discovery with the0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparentsupernova (mag about 17.5) on an unfiltered image taken on Nov.30.5 UT.  SN 2000fa was confirmed (at similar brightness) on anunfiltered image taken by M. Schwartz with the 0.5-m Tenagra IIIautomatic telescope on Dec. 1.2.  The new object is located at R.A.= 7h15m29s.79, Decl. = +23o25'32".5 (equinox 2000.0), which is 5".1east and 5".6 south of the nucleus of UGC 3770.  KAIT images of thesame field taken on Nov. 24.5 (limiting mag about 18) and 17.4(limiting mag about 19.0) showed nothing at this position.SUPERNOVA 2000el IN NGC 7290     T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum of SN2000el (cf.IAUC 7523,7531), obtained by P. Berlind on Nov. 25.13UT with the F. L. Whipple Observatory 1.5-m telescope (+ FASTspectrograph), shows it to be a type-II supernova several daysafter maximum light.  The spectrum consists of a well-definedcontinuum with superposed P-Cyg lines of hydrogen and Ca II.Narrow H-alpha emission superposed on the spectrum of the supernovaindicates a recession velocity of 2970 km/s for the host galaxy.The expansion velocity derived from the minimum of the H-beta lineis 4200 km/s.
