Scientific paper

We present spectro-imaging data of the molecular cloud core M17-North. The data have been obtained with the ISOCAM camera on board of the Infrared Space Observatory (ISO) using the circular variable filters (CVF). The spectra have a spectral resolution of about 40. They are dominated by polycyclic aromatic hydrocarbon (PAH) emission bands. A band at 16.6 μm is detected which is ascribed to the family of the PAH bands. Further, the PAH bands display clearly Lorentzian line profiles. The observations led to the detection of a new mid-infrared source with a very strongly rising continuum. Some information on the morphology of the HII region could be derived from the spatial distribution of the fine structure line emission by ionic species.
