Proper motions for 124 stars within a radius of 3 degrees from Polaris and with relative errors on the parallaxes lower than 15 percent. There are 18 additional stars for which the proper motions fall outside the diagram boundaries. The proper motion of Polaris is indicated by the cross-bars. Errors on the proper motions are in all cases smaller than the dot size. No clustering in proper motions is being observed. The colours of the dots reflect the spectral types of the stars, from blue (B) to red (M).
