Abstract
Ultraviolet (λ∼200 nm) observations of 120 galaxies are performed in a 1.8 square degree field centered on the A 1367 cluster with a 40 cm imaging telescope flown on a stabilized balloon-borne gondola. Total ultraviolet fluxes are obtained and used to derive the current Star Formation Rate (SFR) in the cluster galaxies with measured Hi masses. A good correlation is found between the SFR per unit area and the gas surface density, similar to that previously found for a sample of field galaxies (Donaset al., 1987), while the mean gas depletion time-scale (M g/SFR) is probably shorter in the cluster than in the field.
