subject: SN1993J photometry at Nishi-Harima (4/8 and 4/9)
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. 8.576 UT SN1993J V=11.68 (assuming star B as V=11.90)
star B - star A = +0.50
1993 Apr. 9.659 UT SN1993J V=11.52 (assuming star B as V=11.90)
star B - star A = +0.49
