1 2006MNRAS.368.1757W Possible Blazhko star, period 57d.
2 GCVS Team P var. Before ~JD2437000 Max = 2436078.384 + 0.5630609d*E [V.P.Zessewitsch, Astron. Tsirk. N185, 1957.]; then P changed abruptly. Delta(m) changes by ~0.3m, Max A1 = 2436078.8 + 69.486d*N1, Max A2 = 2437646.65 + 69.719d*N2. Other possible cycles are 2000d (interaction of cycles N1 and N2) and ~30 years [Yu.S.Romanov, V.P.Zessewitsch, L.I. Shakun, P.S.Zgonyajko, Astron. Tsirk. N981, 1978.].
