discov_num notes refcode
BLL 42 Chi Cyg. A is a Mira-type variable.
Smyth published a measure for an additional 9th magnitude component Smy1844
(1835.67, 72.9deg, 25".7) and noted similar measures by Herschel H__1906A
(1779, 24".8) and South & Herschel (1822.49, 63.3deg, 25".5). However, SHJ1906A
ALADIN indicates nothing at the purported location of this object.
These measures appear to have been assigned to 19464+3344 STF2580AB,
instead.
