some brighter in the middle, and bisection fairly accurate.

As the first measure of this is on a single night, relative 
motion is uncertain. The measures should be continued. The 
proper motion of A is small:

This measured to show whether or not C has any proper 
motion. 
The apparent motion of A from the measures of AC (1828- 
I 9 <> 5 ) is:

The only other measures of the Herschel companion are my 
own. Later observations are necessary for correction of the 
proper motion of Jt Cephei.
