     OPTICAL BEHAVIOUR OF THE POLAR ST LEONIS MINORIS=CW 1103+254
                         IN THE SEASON 1988

In linking to the sequence of comparison stars given in the IBVS No. 2735
the star was measured on 17 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 14 February 1988 and 12 May 1988.
The individual observations are listed in Table I. The "fainter than" 
observations marked by > are from plates on which the star is invisible.
