SUPERNOVA 1996cb IN NGC 3510
S. Nakano, Sumoto, Japan, reports the discovery by Masakatsu Aoki,
Tsukioka Cho, Toyama, of a supernova (mag 16.5) on unfiltered
CCD frames taken on Dec. 15.707 UT with a 0.43-m f/6 reflector.  SN
1996ca is located R.A. = 11h03m41s.98, Decl. = +28o54'13".7(2000.0)
which is 20".9 west and 65".7 north of the centre of NGC 3510.
There is no image of the supernova on Aoki's patrol frames taken on
Oct. 24 and Nov. 6, and nothing at this position on the Digital Sky
Survey.

SUPERNOVA 1996cc IN NGC 5673
S. Nakano, Sumoto, Japan, reports the discovery by Shunji Sasaki,
Hasaki-machi, Ibaraki-ken, of an apparent supernova (mpg = 15) on
two 4-min T-Max 400 films taken on Dec. 19.769 and 19.773 UT with a
0.20-m f/4.8 reflector.  Sasaki reports the new star as being about
20" northwest of the centre of NGC 5673, noting that a brighter
foreground star (mag 12.5) is located about 40" northwest of the
galaxy's nucleus.  Sasaki's patrol films in 1996 show no star at
the location of SN 1996cc.  R. Kushida, Yatsugatake South Base
Observatory, confirms the presence of SN 1996cc (at mag 14.9) on an
unfiltered CCD frame taken on Dec. 20.733; nothing was present at
this location on a similar frame taken on 1996 May 25.
Y. Kushida provides the following measurement of SN 1996cc from the
Dec. 20 exposure:  R.A. = 14h31m28s.45, Decl. = +49o57'43".8
(equinox 2000.0), which is 25" west and 14" north of the galaxy's
centre. A star of mag 15 is located at position end figures 30s.0,
35".
