Cross-ID: Gaia DR2 1939127057829196672
2" visual binary in Gaia DR2.
Large parallax quoted by
2016AJ....151..160F
(177.9+-24.1 mas) is likely to be spurious due to unresolved binarity (as noted in their table). Gaia DR2 resolves the 2" pair, and estimates parallax 0.1916+-0.0377 mas to 2MASS J23402010+4631110.
Hence this is unlikely to be a nearby star.
