Our polarimetry data revealed an extended (up to ∼5') polarized nebula over S106. We confirmed the position of the illuminating source of most of the nebula as consistent with S106 IRS 4 through an analysis of polarization vectors. The bright portion of the polarized intensity is consistent with the red wing component of the molecular gas. Description: The observations of S106 were carried out on 2006 June 15 with the imaging polarimeter SIRPOL, the polarimetry mode of the Simultaneous 3color Infrared Imager Unbiase Survey (SIRIUS) camera, on the 1.4m Infrared Survey Facility (IRSF) telescope at the South African Astronomical Observatory (SAAO).
