12CO J=2-1 maps of L379 IRS1 show a molecular outflow seen almost end-on while C18O J=2-1 emission covers a smaller central region, tracing virially bound material deeper within the cloud. Continuum maps at 450, 800 and 1100µm all trace an identical double peaked arc west of IRS1 and VLA NH3 (1,1) & (2,2) integrated intensity maps reveal the same double-peaked structure. An identical velocity gradient is seen in12CO,13CO, C18O and NH3 (1,1) & (2,2) following the arc-like structure of the continuum emission.
