Subject: SN1993J photometry at Nishi-Harima (4/7)

    M. Okyudo and T. Ishida (Nishi-Harima Observatory, Hyogo, Japan)
obtained following differential photometry of SN1993J using 0.6-m
reflector + CCD.  The supernova was confirmed to be on the rise.
    The color band is Johnson V (uncalibrated, but the color system
is very close to the standard V).

    1993 Apr. 7.610 UT   SN1993J  V=11.69 (assuming star B as V=11.90)
                         star B - star A = +0.49
