An extended diffuse feature north-east of IRS 3 displays a remarkable S-shaped structure. This feature is the innermost part of an at least 15'' long extended structure, which is pointing towards a bow-shock like patch located 90'' away from IRS 3. We find strong H_2 line emission associated with this feature, suggesting the presence of shocks, caused by the collision of outflowing material with the ambient medium. The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a.
Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. Some of these features also exhibit strong H_2 line emission, demonstrating that IRS 3 drives outflows in several directions.
