Abstract
Two fields near the Galactic Center, containing the Quintuplet and Object #17 star-clusters, have been imaged with the ISOCAM circular variable filters (CVFs). Emission of [Ar II] 6.99 μm is detected in the “pistol-shaped” H II region (G0.15–0.05) to the south of the Quintuplet cluster. In the Object #17 cluster field, a region ∼40″ north of the cluster center is bright at 7.0 μm and 12.8 μm. We identify these to be the [Ar II] and [Ne II] lines. In addition, this region has the Unidentified Infrared Band emission at 6.2, 7.7, 8.6, and 11.3 μm. This region is bright also in the 6mm continuum, and probably the site of interaction of the UV radiation from the Object #17 cluster with the ambient molecular cloud.
