Abstract
The region S106 = G 76.4 — 0.6 has been photographed in the 8000Å region with the Carnegie image converter attached to the 0.6m telescope at the Mees Observatory. This was done in connection with a larger program designed to assemble radio, infrared, and optical data on compact HII regions.S106 has angular dimensions of 1’ by 3’ and has relatively high surface brightness. Its kinematic distance based on H109a observations (Reinfenstein, et al. 1970) is 2.3 kpc ± 3.0.Several bright maxima are observed within the nebula at wavelengths of 12.6/x and 2.7 GHz. These are believed to be the result of thermal radiation from hot dust and free-free emission from ionized gas, respectively. At the nominal distance their linear sizes are of the order of 0.2 pc and they may be similar to the “cocoon” type objects discussed by various authors.
