Van Biesbroeck (1954) was unable to resolve this system in 1943, |
|
|
1944 or 1945 on the 82-inch telescope at the McDonald Observatory. |
|
|
However, since he resolved the system successfully in 1946 with the |
|
|
same telescope, and in 1940 with a smaller (40-inch) telescope, the |
|
|
non-resolution is probably due to bad seeing or ID error. |
