Dear SN watchers,

  Successive nearby supernova discovery is continuing.  Perth team has
found a new apparent supernova 1999ca in southern face-on Sc galaxy
NGC 3120, as reported in IAUC 7158.

  The location of SN 1999ca is: R.A. = 10h05m22s.92, Decl. =
-34o12'41".3 (2000.0), which is about 32" north (slightly smaller than
IAUC value) of the center of NGC 3120, and coincident with the
northern edge of the optical spical disk.  This galaxy is near from
the Galactic plane (b = 17o.1), so there are many foreground stars,
but the confusing one isn't there.  

  The reported magnitudes are;
19990402      >19
19990427.55    17:R
19990430.514   170C .

  The recession velocity of NGC 3120 is an order of 3000 km/s, which
indicates that typical SNeIa on this distance would be 14.5 mag or so
at their maximum light.  Followup observation is encouraged.

Sincerely Yours,
