    SN1993J photometry at Nishi-Harima (4/11-12)

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

    1993 Apr. 11.659 UT   SN1993J  V=11.30 (assuming star B as V=11.90)
                          star B - star A = +0.49
    1993 Apr. 12.557 UT   SN1993J  V=11.24 (assuming star B as V=11.90)
                          star B - star A = +0.49
