This compact HII region lies embedded in the molecular cloud complex NGC 6334 and is totally obscured in the visible. Its radio thermal emission has an extent of about 20 arcsec. As other compact HII regions observed with sufficiently high angular resolution, this source shows a lack of emission in its central part, indicative of the presence of a cavity. Although the mechanism responsible for this is still poorly understood, the presently favored mechanism is the existence of powerful winds from the central star or stars (undetected in the radio). These winds push away nearby gas and give the HII region a "shell" or "ring" geometry.
Observing run - 1980 April 15-16 at the VLA in the A-configuration using 21 antennas.
