Photometry in V and B with a 16-inch automatic telescope from 1988 to
1991 confirms the synchronous rotation suspected earlier and reveals v
ariability up to 0(M).10 in the B bandpass at one epoch. Five spots fo
rmed with lifetimes ranging from 0.15 to 0.77 years. As with other rap
id rotators, the differential rotation coefficient (k = 0.03) is signi
ficantly smaller than that of the Sun (k = 0.19).
