SUPERNOVA 2007oc IN NGC 7418A
     F. Olivares, University of Chile; and G. Folatelli, Las Campanas
Observatory, on behalf of the Carnegie Supernova Project, report that a
spectrum of 2007oc (cf. CBET 1114), obtained on Nov. 4.0 UT with the European
Southern Observatory 3.6-m telescope (+ EFOSC2) at La Silla, shows this to be
a type-II supernova similar to SN 1999em at about 25 days after explosion.
The absorption component of the H-alpha line is weaker in 2007oc than in
1999em.  Adopting the NED recession velocity of 2102 km/s for the host galaxy
(from Da Costa et al. 1991, Ap.J. Suppl. 75, 935), the maximum absorption of
the H-beta line indicates an expansion velocity of about 8000 km/s.
