Magnetic fields play important roles in the formation and evolution of interstellar clouds and protostars. Polarized dust emission is a key tool for measurement of magnetic field morphology. I will present the first measurement of the magnetic field in the LkHα-101-S region from polarized dust thermal emission. The LkHα-101-S region is one of the densest regions with an early-B star in the Auriga cloud, a nearby giant molecular cloud of the Gould Belt. This study is a part of the “B-fields In STar-forming Region Observations” (BISTRO) survey which is a large program of the James Clerk Maxwell Telescope (JCMT). The polarized dust thermal emission was taken by the POL-2 polarimeter at 850-micron wavelength. The morphology and strength of the B-field have been obtained. We applied two methods to calculate the B-field strengths, un-sharp masking and structure function, and they gave consistent results.
