[Kozo Sadakane <sadakane@cc.osaka-kyoiku.ac.jp>]

Dear colleagues,
 
We obtained 30 CCD images of NGC2962 using the 50-cm
reflector at Osaka Kyoiku University from 11.49 to
11.68 (UT). Johnson V and Cousins R, I interference 
filters were used. Preliminary magnitudes of SN1995D
were obtained relative to a star (GSC mag. = 13.9)
locating at 3' 52.9" west and 1' 1.9" north of the SN.
Magnitudes were obtained using the APPHOT routine in
IRAF.
Results are as follows.

It is interesting to note that the SN brightened by about
0.1 mag in the V-band within 5 hours.
