1 GCVS Team In 1971 - 72 the observations were described by the combination of the tabulated elements (period P1) and the following systems of elements: Max = 2441296.0705 + 0.251300d*E, (P2); Max = 2441296.032 + 0.23904d*E, (P3); Max = 2441296.065 + 0.12501d*E, (P1/2); Max = 2441296.124 + 0.12565d*E, (P2/2). Beat periods: 49.198d, 5.442d, 4.900d. Since 1908 P1 increases, P2 decreases. 12 overtone and resonance periods were found in [A.van Hoof, ZsAp 56, 27, 1962.].
