Abstract
The autocorrelation method is applied to the observed va- riation of the solar diam eter. The results substantially agree with those obtained by M. Cimino. The period of th e variation is around 23 years, bu t this is not a period in a stric t sense. The phase shift betw een th e variations in diam eter and th e va riation in sunspot num bers is confirmed
