Abstract
Portions of the nebula NGC 2024 were mapped in the 157 micron (C II) line. Results show the presence of a compact component centered on the radio-recombination line regions and a more extended nebulosity. It is found that the central component emits 157 micron line and continuum fluxes at a level of 4 x 10 to the -16th W/sq cm and 5 x 10 to the -16th W/sq cm (micron), respectively. The continuum emission drops off more rapidly with distance from the peak, although line emission is approximately 30% of the peak value at a distance 18 min to the SE of the peak. In addition, related observations were carried out on M42.
