- We examine the astrometric measurements and physical properties of ~2.5 million stars with proper motions larger than 40 mas/yr, which were originally charted in the SUPERBLINK proper motion catalog, and for which data from the GAIA second release (GAIA DR2) is now available. These represent the stars with the fastest proper motions observed by GAIA, the vast majority of which consist of low-mass K and M dwarfs in the vicinity of the Sun (d<200pc). We find that the GAIA proper motions are in excellent agreement with the SUPERBLINK values, and show how the new GAIA parallaxes and optical magnitudes significantly enhance the all-sky census of faint stars with large proper motions.
