The velocity field of the giant H II complex NGC 2363 in the SBm galaxy NGC 2366 has been mapped in the forbidden O III 5007 A line using a scanning Fabry-Perot interferometer. The forbidden O III line profiles correspond to symmetrical and single component profiles in most of the nebulae of NGC 2366, except in the bright core of the giant H II NGC 2363 where strong splitting of the line occurs. This splitting is consistent with a bubble 200 pc in diameter expanding with a velocity of 45 km/s. The total kinetic energy of the bubble is 2 x 10 to the 52nd ergs; the kinematic age of the bubble is less than or equal to two million yr. The bubble could be produced by the sole action of combined stellar winds from the central clusters of OB stars. A well-defined sector, 150 pc wide, of the H II complex originating at the bubble shows systematic receding velocities; it is suggested that this region acts as a vent through which gas escape into the halo of the galaxy. Large H-alpha shells are observed in the surroundings of NGC 2363. There is also evidence for a very broad and low-entensity forbidden O III high-velocity component associated with the bubble.
