1 GCVS Team Mean interval between the supermaxima is 179d. Porb = 0.0742711d. Between the normal outbursts the brightness periodically increases by 0.35m - 0.40m because of hot spot appearances: Max = 2440128.0222 + 0.0742711d*E [B.Warner, MN 170, 219, 1975.]. During the supermaxima the period between the superhumps is 0.0769d [N.Vogt, AG Mitt N57, 79, 1982.]. Sometimes the light oscillations with the amplitude 2% and cycle from 28s to 34s are observed [B.Warner, A.J.Brickhill, MN 166, 673, 1974.].
