and 1907 we have the proper motion of A:

Vogel’s nebula (Dreyer 3332) is about 25' nf 02 224. This 
does not appear to belong to the planetary class, but has a 
small central condensation, and is therefore capable of accurate 
comparison with the micrometer.

The following is from A R. A. and A Decl. and not direct 
measures, and hence no motion is to be inferred.

The proper motion of A from meridian positions is not likely 
to be correct.

The proper motion of the large star from meridian positions 
seems to be too large. The five sets of measures of the small 
star (1880-1909) give: 
o'.'io5 in 262 ?o 
This will be confirmed in the future by further measures of 
C and D.

No other measures. About 35 's of H 2542 is li 738, which is 
double, or has a double nucleus; the smaller from the other 
247?8: is'.'s. For this Engelhardt gives 253?6: 13C5 (1888.38). 
The brighter of the two may be a small star.

The star is measured from the bright nucleus. It is probable 
that the center of the nebula was used by the earlier observers.
