     UBV OBSERVATIONS OF NOVA CYGNI 1978



Nine UBV observations of Nova Cygni 1978 have been made during
two nights in September 1978 with the Lund Observatory 61-cm
Cassegrain-Nasmyth reflector. The results are given in Table 1.
The comparison star was HD 204102. The adopted magnitude and
colours of this star were: V=8.02, B-V=0.10 and U-B=0.05.

           Correction to IBVS No. 1522


    The formulae on page 3 should read :
       "tg beta = [(1-r) / (1+r)] cotg i and
              r = H_e(min) / H_e(max)"

According to my new calculations I have obtained a more accurate
value for beta:

            beta=73deg +- 3deg
