A 1 μm CCD picture and maps of the Ne II and Ar III fine-structure lines have been obtained in a region roughly one arcminute in size entered on the core of the compact H II region G333.6-0.2. The two emission-line maps show nearly identical intensity distributions, although much different fluxes. The maps are similar to the 1 μm picture smoothed to their angular resolutions. The infrared line of S IV also was detected and appears to have a spatial intensity distribution similar to that of the other fine-structure lines. The 1 μm picture reveals a small number of objects of nearly stellar appearance in the core, suggesting that G333.6-0.2 is powered by a compact cluster of sources. Stellar continuum radiation probably is responsible in part for the low equivalent width of the Bγ line in the core.
