An unusual circular region of very filamentary nebulosity, 3.5 pc diameter, exists on the southern edge of the interstellar complex of NGC 6334. This surrounds an O6.6 star. Narrow band, Schmidt photographs centered on the H-alpha and N II and S II forbidden band lines, a Fabry-Perot interferogram of the N II forbidden band line, three intermediate dispersion (10 A/mm) AAT spectra, and VLA measurements, have now been obtained of this object. Many components over a range in radial velocity of 150 km/sec are found over the face of the nebula. As this nebula is a thermal radio source and the line ratios imply radiative ionization, energetic stellar winds and radiation pressure from Lyman photons are a possible source of these motions.
