             27 Vir: A POSSIBLE DELTA SCUTI STAR

    The star 27 Vir = BS 4824, classified Var? by the Bright
Star Catalogue, was observed photoelectrically in UBV system with
the 60 cm reflector of Bologna Observatory for 5 hours in the
night February 7-8, 1975 using 30 Vir and 31 Vir as comparison
stars. The differences of magnitude 27 Vir - 30 Vir are plotted
in the figure.
    The rapid light variations with P = 0d.05 having the same
amplitude of 0m.02 in U,B,V and the spectral type A5 suggest that
27 Vir is a delta Scuti variable.
