    Spectro-polarimetric observations with the Solar Optical Telescope onboard Hinode reveal the emission spectrum of the Fe i 630nmlines at the solar limb. The emission shell extends for less than 1 arcesc thereby making it extremely difficult to detect from ground-based observatories viewing the limb through the Earth’s atmosphere. The linear polarization signal is clearly due to scattering and it is predominantly oriented in the radial direction. Using a comprehensive atomic model of iron, we are able to interpret qualitatively the observed signals, including the radial orientation of the linear polarization.
