NGC 4151 is a Seyfert 1.5 galaxy. Due to its proximity of only 13 Mpc it is an ideal testbed and therefore one of the most intensively studied Seyfert galaxies. NGC4151 shows an outflow in the Narrow Line Region (NLR) along the NE and SW direction. This outflow has been modelled by several authors ([9], [10] and [11]) as two hollow bi-cones. The excitation conditions in the NLR have been investigated by [11] and have been attributed to photoionization due to the central engine. [4] also observed a linear radio structure in the inner few parsec with a pronounced S-like curvature which is slightly misaligned with the bi-cones major axes. Here we compare these findings with our results and discuss the role of the radio jet. We also refer the reader to the full paper (Iserlohe et. al., 2012) which will be published soon.
