Resumen:
We have redetermined with a resolution of 0.21 Å /px, the V sin i values of 1060 B-type stars of the northern hemisphere brighter than V = 6.5. We have also included some southern objects to the north of -31 degees for overlapping with the southern survey which is underway. The V sin i values were derived by comparison with standard stars in the Slettebak system and we have used for such purpose 4471 and 4481 lines from HeI and MgII respectively. We have also measured the equivalent widths of the lines. A statistical analysis will follow.
