SUPERNOVAE 2000ff, 2000fg, 2000fh, 2000fi, 2000fj, 2000fk, 2000fl
     Further to IAUC 7529, L.-G. Strolger reports the discovery of
seven additional apparent supernovae by the Nearby Galaxies
Supernova Search team.  Direct confirmations were made by Strolger
and R. C. Smith (Kitt Peak 0.9-m telescope) on Nov. 11-19 and 22
and by P. Candia (Cerro Tololo 0.9-m telescope) on Nov. 18 and 19.
Direct images obtained with various other telescopes indicate that
SN 2000fg had brightened to R about 18.2 on Nov. 28; that SN 2000fh
appeared to be at or near maximum light (R about 19.2) on Dec. 1;
that SN 2000fk appeared to be just past maximum light at R about
19.8 on Dec. 1; and that SN 2000fl appeared to be still rising at R
about 18.8 on Nov. 30.
