Scientific paper

The chromospherically active star, Delta CrB, has been optically variable for several years. It has now been found that the period of this variability increased over four years at the rate of about 10 days/year but that in the fifth year the variability ceased. The average brightness of the star over the same interval has varied by about 4 percent in what appears to be a roughly five-year cycle. A speculative explanation in terms of active regions and differential rotation is considered.
