Spectrophotometry of the H II region G333.6 – 0.2 with λ/Δλ≏100 shows strong emission lines of hydrogen and helium super-imposed on a continuum. Spatial variations in the equivalent widths of the lines suggest the presence of very hot (⁠⩾600K⁠) dust grains within the region. The shape of this very powerful H II region indicates that its dense ionized core is being continuously replenished from a reservoir of neutral gas.
