First resolved by Lewis in 1902, this system was unconfirmed for |
GrO1932A |
|
several decades despite numerous attempts, notably those of Aitken |
|
|
with the 36inch between 1910 and 1922. In the ADS, Aitken concluded |
A__1932b |
|
"It is very doubtful whether the star is double". The system was |
|
|
subsequently removed from the WDS, until its resolution by Prieur et |
|
|
al. over 90 years after its discovery. |
