(1993 May 25)
subject: CCD observations of Nova Oph 1993
Following differential magnitudes have been obtained at Ouda Station
(Nara, Japan), Kyoto University.
1993 mid-UT band Nova-"a" N
May 24.6714 V +2.63 +/- 0.01 3
24.6851 Ic +1.73 +/- 0.01 3
24.6968 B +2.69 +/- 0.02 2
If we take the magnitudes of "a" as V=11.05, Ic=10.51, B=11.58,
the magnitudes of the nova become:
V=13.68, Ic=12.24, B=14.27 (B-V=+0.59, V-Ic=+1.44)
(uncorrected Ouda system)
