This rather uninspiring pair of stars seems to pose a bit of an enigma
as regards the magnitude of the B component, which the WDSC gives as
9.3, however there are three other stars in the same field, to the
immediate south is TYC 3595-1951-1 mag 10.66; south of that, TYC
3595-1968-1 mag 10.49; and, to the north of the double,GSC 3595-1701
mag 10.72 (I am aware of the unreliability ofthe GSC mags) however all
three of these stars seemed to corespond with the text, and all three
were brighter than the B star, the GSC by about .2 mag.
So is then the B star a variable? or is,perhaps the WDSC text
innaccurate in this instance? Something to keep an eye on perhaps.
