We present our recent results of the high dispersion spectroscopy of a Galactic halo planetary nebula, K 648, in the globular cluster M 15. The position-velocity diagrams of our spectra indicate the existence of collimated outflows in K 648. In the [N II$\lambda$6583 diagram, we found high velocity components with a velocity $\sim$60 km s$^{-1}$ in the central region of K648.
