No other measures, h 8 is 2 m 50 5 / H 1941, with nearly the 
same declination. It has a 10.im star in the center like the 
planetary nebulae. Its place is found from the following stars:

A small common proper motion. All the earlier measures 
are given in G. C. Part II. The proper motion of the principal 
star (Groombridge 30) is given:
