Magnetic Fields in Star-forming Molecular Clouds. IV. Polarimetry of the Filamentary NGC 2068 Cloud in Orion B

We present submillimeter polarimetry at 850 μm toward the filamentary star-forming region associated with the reflection nebulosity NGC 2068 in Orion B. These data were obtained using the James Clerk Maxwell Telescope's Submillimeter Common-User Bolometric Array polarimeter. The polarization pattern observed is not consistent with that expected for a field geometry defined by a single mean field direction. There are three distinct distributions …
