We have observed the star GSC 
to investigate whether it is
in a binary with PSR B1929+10. Its spectral type is K4-6 and its
luminosity class is III or II, therefore its distance is 2.4 kpc or
higher. Since the dispersion measure distance of PSR B1929+10 is 0.17 kpc,
we rule out the possibility that these two stars are associated
in a binary. This poses further constraints on the lower limit of kick
velocities in supernova explosions.
Key words: stars: individual: GSC 01060 / 01374 / stars: neutron / pulsars: individual: PSR B1929+10
