Remark: d = 0.04 P. VB A (B 14.0m, 30", 225deg, 2008; C 11.3m, 43", 276deg, 2008; D 12.0m, 45", 316deg, 2008). Probably eclipses are caused by a gas and dust disk. Besides eclipses, quasi-periodic brightness variations with an amplitude of several tenths of a magnitude and a cycle of 105 - 120 days (e.g., [N0204]). More rapid variations were also reported.
