      PHOTOMETRIC BEHAVIOUR OF DR TAURI IN THE SEASON 1987/1988

In completing and supplementing the light curve in B the star was measured
on 21 blue-sensitive plates (ORWO-ZU21+GG13+BG12) from 11 nights obtained
with the 50/70/172 cm Schmidt camera of Sonneberg Observatory covering the
time interval between 2 October 1987 and 9 March 1988. The measurements,
which are listed in Table I and which are given in the light curve in
Figure 1 are linked to the previous sequence of comparison stars given by
Gotz (1982).

                            [FIGURE 1]


  The light curve shows the star in an active phase, which is characterized
by short time scale light depressions and brightness increase. The mean
brightness of the star in the season 1987/1988 amounts to mB= 11.90m at a
total amplitude of DeltamB = 1.37m.
