Global magnetic field morphology in LOSFR. The layered texture in the image represents the magnetic field geometry using submillimeter polarization, and the black vectors overplotted on the Planck submillimeter polarization map correspond to the optical magnetic field geometry using the observed R-band polarization. The red star shows the position of λ-Ori. The clouds BRC 17 and BRC 18 are identified. A 2% degree of polarization reference vector is shown for the optical polarization. The image was taken by the ESA Planck satellite (image credit: ESA and the Planck Collaboration).
