Abstract

Two new times of the minimum allow us to establish, without doubt, the existence of an apsidal motion in this system; the apsidal period being about 1490 years with an error of 11%. We establish a more accurate value of the orbital period and of the periods of principal and secondary minima. On the basis of these periods a new estimate of the times of minima of Kron's light curve is made. We briefly describe a new light curve we have obtained.
