Proper motion measurements of the cool and ultracool populations in the Upper Scorpius OB association are crucial to confirm membership and to identify possible run-away objects. We cross-match samples of photometrically selected and spectroscopically confirmed cool and ultracool (K5<SpT<M8.5) candidate members in the Upper Scorpius OB association using the literature and the USNO-B (Cat. ) and the UCAC2 (Cat. ) catalogues. 251 of these objects have a USNO-B and/or UCAC2 counterpart with proper motion measurements.
