Remark: Min II 6.43; Min II - Min I = 0.5018P; dI = 0.045P; DII = 0.13P; dII = 0.00P. P var. Min I = 2426624.378 + 1.983244d*E (JD2415300 - 26800) [09309]; Min I = 2429535.739 + 1.9832125d*E (JD2426800 - 36000) [09312]; Min I = 2437018.414 + 1.983252d*E (JD2436000 - 37500) [00001]; since JD2437500 - see Table. There is a square term in the elements given in the Table: - 5.24d*10**(-9)*E**2. Shape of the light curve varies; there is a distortion wave with A up to 0.13mV migrating in the direction of decreasing phases with P ~2.5 yr. Spectrum investigations [01816, 09315, 9316].
