We present the observation of a new intermediate redshift damped Ly[FORMULA] absorption system candidate, discovered in the course of a spectroscopic follow-up for identifying the sources detected in a 150Å-wide bandpass UV-imaging survey at 2000 Å. The system displays very strong Mg II and Fe II lines and a high Fe II /Mg II ratio, which, following photoionization models, indicates a very high neutral hydrogen column density. Such systems being very rare at redshifts [FORMULA], but of prime importance for the understanding of the evolution of star formation in galaxies, the newly discovered candidate deserves further investigation in a near future.
