Abstract
Radial velocities from the Hα line using a photographic Fabry-Perot equipment are obtained at 625 points of the H II complex NGC 2467, in the constellation of Puppis. The region studied covers around 400 sq. arcminutes. Two galactic clusters, H 19 and H 18ab, are associated with the H II complex. A kinematic distance of 4.2 kpc is derived using the mean of the Hα velocities. This distance is exactly the value given by Havle'n for the Pup OB2 association which delineates a spiral feature. Relative velocities are detected between the different sections of the nebula, up to 10 km s-1 in the radial direction. There is indication that the gas surrounding the O6 star HD 64315, the main source of excitation of the densest part of the H II region, is expanding. An expansion is also detected of the compact H II knot surrounding the star B1 V in the cluster H 18ab. The whole complex is a young object with age around 2 - 3 x 10^6 years.
