GCVS NOTE result

d = 0.04 P. "VB A (B 14.0m, 30"", 225deg, 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.
