               UBV OBSERVATION OF NOVA ANDROMEDAE 1986

M. Suzuki (Ena City, Gifu, Japan) discovered a nova of m = 8.0 at
alpha = 23h09.5m, delta = +47d10' (equinox 1950.0) on Dec. 5.44 (UT), 1986. After the
maximum light, we observed the nova in UBV colours with the 40-cm reflector
of the Science Museum of Kawasaki on Dec. 11 (UT), 7 And was used as the 
comparison star.
  The obtained differential magnitudes in the sense of Nova - 7 And are
given in Table I, which are also plotted in Figure l.

   Our observation indicates the existence of some increasing light. It is also
found that the B-V colour is becoming redder with time while the U-B bluer.
