of the strength of the stellar magnetic field—this system has an estimated age of 1.14 billion years. Changes of distance and position angle This table shows the apparent distance between the two stars and their relative position angle: the first three columns show data predicted from an orbit calculated in 1937, the next two columns show in 2006, the next three columns show observations reported by the Hanwell Community Observatory.
