CHE 27 |
This pair has opened considerably since its discovery (from 9".6 to |
Che1910 |
|
19"), due to the considerable proper motion of the primary. AC2000 |
|
|
coordinates of both components from ~1901 are in good agreement with |
|
|
Chevalier measure, so identification with this pair appears probable. |
