A new bipolar outflow source in OMC-1

Observations of the J = 2-1 and J = 5-4 transitions of SiO have been made toward the outflow source about 1.5 arcmin south of Orion-KL, using the IRAM 30-m telescope, with 25- and 13-arcsec resolution, respectively. Additional measurements of the J = 2-1, 3-2, and 5-4 lines of C34S and observations of J = 5-4 and J = 13-12 transitions of CH{sub 3}CN have been made with the 30-m telescope. The SiO data clearly indicate that a separate outflow source exists about 100 arcsec S and 20 arcsec W of the Orion-KL/IRc2 position. 17 refs.
