Planck Polarization Data

The Planck polarization data satus will be described. Due to rapid progresson the systematic effects affecting them and calibration (absolute and relative) the polarization data which will be delivered in the fall of this year are bringing a new view of the microwave sky.

The data on polarized emission from interstellar dust will be presented (Cosmology results will only be public in the fall).

The statistical properties of dust polarized emission at high latitude, which are critical for the detection of primordial B modes, will be described. The implications for the recent BICEP2 paper will also be discussed.
