| Abstract: |
We have obtained the first direct measurement of the continuum polarization
near the extreme limb using the Helioseismic Imager (HMI) on board the
Solar Dynamics Observatory (SDO). The polarization is small (much less than
1%) but easily distinguished from statistical and systematic noise sources.
These measurements differ from previous attempts to measure small
continuum polarization that depended on a model of line polarization to
infer the continuum (cf. Stenflo 2005) polarization. |
