Barris, University of Hawaii, on behalf of the High-Z Supernova Search Team (cf. IAUC 6160, 6646, 7312, 7516, 7745, 7755), reports the discovery of several apparent supernovae on I-band images taken with the Canada-France-Hawaii Telescope (+ 12K Mosaic in queue mode); the supernovae were identified by subtracting images taken on Sept. 11 and Oct. 9 and 13 from those taken Nov. 12, and confirmed on images obtained by P. Challis and E. Martin (Subaru telescope + SUPRIME) on Nov. 18, 19, and 23. Spectral observations were made with the Keck II telescope (+ ESI) by R. Ellis and M. Sullivan (Nov. 13) and by A. V. Filippenko and R. Chornock (Nov. 18 and 19). SNe 2001hn and 2001ho were discovered in the Sept./Oct. data (cf. IAUC 7745) and are now extremely faint. In the table below, I_D is the discovery I magnitude, and I_L is the magnitude determined on 2001 Nov. 18 (or Oct. 9 for SNe 2001hn and 2001ho). The tabulated redshifts are for the host galaxy's emission. Each apparent supernova is within 2" of its host galaxy's center. SN 2001 UT R.A. (2000.0) Decl.
