1 GCVS Team VB A (B 13.3m, 4", 138deg; C 58", 24deg). In the bright nebula NGC 6726/27. P = 1.92d is not excluded, in that case Min II = Min I. On the basis of visual observations 8.7 - 12.4 v (presumably "spurious variability" due to the difficulties of estimates over the bright background of the nebula), and the star was classified as INSA.
