SUPERNOVAE K. Schahmaneche, University of Paris VII, reports the discovery of

17 supernovae and five apparent supernovae by the Supernova Cosmology Project. SN 2000fr was discovered two weeks before maximum light and confirmed spectroscopically with the Keck II telescope (+ LRIS) and the Very Large Telescope UT1 (+ FORS1) on 2000 May 2 and 12.

The following 2001 supernovae were discovered at the Canada-France-Ha-waii Telescope (in coadded images taken during 2001 Apr. 15–20, after subtracting coadded images from Mar. 29–31) or at with the Blanco Telescope at Cerro Tololo (in coadded images taken during Apr. 18–20, after subtracting coadded images from Mar. 28–30):
