      THE OPTICAL BEHAVIOUR OF KR AURIGAE IN THE SEASON 1986/87

   In supplementing and completing the light curve in B given by Gotz (1983,
1984, 1985, 1986) the star was measured on 44 blue-sensitive plates (ORWO-ZU21
+ GG13 + BG12) from 25 nights obtained with the 50/70/172 cm Schmidt camera of
Sonneberg Observatory, covering the time interval between 5 September 1986 and
30 March 1987, using the comparison star sequence given by Popova (1965). The
observations are listed in Table I and shown in Figure 1.
   It can be seen from Figure 1 that KR Aurigae was in an extremely high state
during the whole time of patroling. Most of the observations are brighter than
mB = 13.0m. Visual observations of the star given by Verdenet, Mizser and 
Monella (1987) are marked by circles in Figure 1.
