Light variations with Porb and amplitude up to 0.9mV due to eclipses of hot spot are represented by the elements: ET(Min) = 2437699.94177 + 0.0682338422d*E, where ET(Min) is the heliocentric Julian Date converted to Ephemeris Time; simultaneously periodic modulation of the shape of the light curve between the outbursts is observed with the amplitude 0.2m - 0.9m and the elements: Max = 2437699.8895 + 0.04654656d*E - 1.2d*10**(-12)*E**2 [C.Sterken, N.Vogt, R.Freeth, H.D. Kennedy, B.F.Marino, A.A.Page, W.S.G.Walker, AsAp 118, 325, 1983.]. Mean interval between bright outbursts is 465d [F.M.Bateson, A.F.Jones, B.Menzies, NZ Circ N159, 1970.], mean cycle is close to 20 - 30d.
