J-K= 1.82 plus 2-mag. fadings recorded in the original reference and in AAVSO data suggest this is a YSO displaying UXOR-like variability. There is a 8" visual binary to the E of the variable made up of 2MASS J19353621+0633471 (V=12.65; sep. 20") and 2MASS J19353568+0633466 (V=13.40; sep. 12")
ASAS-3 data is for the blend of the three stars and show variability with P= 39.05 d., probably coming from the brightest star rotation. |
