Abstract
We present new observations on several wavelenghts of the central part of LGG 334 wich are much deeper than previous observations. The 21-cm line of neutral hydrogen is observed for 4x12 hours with the Westerbork Synthesis Radio Telescope (WSRT). At low spatial resolution (~60"), the radio data reach a limiting column density of 0.5x10 -18th cm -2 (1o), while at high spatial resolution (~15"), a 1o limiting column density of 4x10-18th cm -2 is reached. Beside the known group members, eight other H1 complexes are detected.
