MCA 65 59 Cyg. A is an irregular variable, V832 Cyg, and an interferometric
binary. B is BD+46@3134.
STF2743 AB: H 4 22. MEv2010
AD: A 71" measure by Guillaume (1931) was incorrectly assigned to AD, Gui1931
resulting in later measures of that wide pair being similarly labelled
as AD measures. These pairs have now been assigned to STF2743AE. A
"rediscovery" of the 39" AD pair by Fay (2013) was incorrectly given FyM2013d
the designation FYM 99AE. This measure has been merged with AD.
