Present observations shows short time variability. There is a strong correlation between jet geometry and polarization. The observed level and orientation polarization changes after the jet-break-time. The polarization should be highest during the break and turn by 90 degrees. However, no firm conclusions exist due to the lack of time-resolved observations of the polarimetry. The degree of polarization is given by the geometry and the orientation of the system and time-resolved data during the outburst will clarify the mechanism during the ourburst. In addition, internal shocks change the degree of polarization. Measuring polarization gives information about the physics happening afterwards.
