Epoch of Max brightness is given. Light variations with Porb = 0.1496263d are superimposed by variations with P = 858.6861s and twice smaller amplitude (Max = 2444815.00276 + 0.009938496d*E; M-m = 0.54P), and also by still smaller oscillations with P = 805.2059s (Max = 2444815.00294 + 0.009319513d*E). The last period is the X-ray impulse period which is equal to the period of rotation of the compact object (probably a white dwarf).
