One of these three components found by Weigelt is probably B 2256; |

however, it is not clear which one due to the lack of a continuous |
|
|
series of observations and orbital motion. |
|
|
This famous luminous blue variable is not classified as an O star, but |
|
|
it is almost certainly a massive object. The inner structure of the |
|
|
ejecta of this star is described by Davidson et al (1997 AJ 113, 335). |
|
|
A preliminary set of orbital elements is given by Damineli et al. |
|
|
(1997 NewA 2, 107), who suggest a 5.5-yr orbit with a maximum angular |
|
|
separation of 0".004. The central object appeared single in our |
|
|
observations. The H component (HDE 303308) was also observed and |
|
|
appeared to be single. |
