Scientific paper

The 400 micron emission from the central region of OMC-1 has been mapped with 35 resolution. This region contains two emission peaks with sizes of about 0.5 arcmin, separated by approximately 1.5 arcmin which probably represent distinct density condensations in the molecular cloud. Comparison of observations with earlier far-infrared observations shows the two condensations to have similar optical depths and dust masses. A bar of 400 micron emission is found about 15 arcsec SE of the ionization front near Theta 2 A Ori, indicating a sharp increase in dust density in the neutral matter outside the ionized region.
