1 GCVS Team Min II 9.49. P var. Min I = 2434455.3872 + 1.583217d*E (JD2411760 - 34455) [H.Schneller, AN 286, H.3, 97, 1961.]. Since JD2434455 - see Table. The two sets of observations are equally well represented by the formula: Min I = 2440628.3643 + 1.5832212d*E + 1.7d*10**(-10)*E**2 [A.Guarnieri, A.Bonifazi, P.Batistini, AsAp Suppl 20, 199, 1975.].
