介绍了2011年10月Blazar S5 0716+714多波段爆发期间的光学（R波段）测光和偏振监测结果以及利用费米γ射线数据对该天体沿着成像的结果。我们分析了总的和偏振强度图像的blazar与VLBA在43 GHz期间和爆发后获得。线偏振矢量以每晚1.50 °的速率单调旋转，与γ射线和光通量的急剧最大值相吻合。与此同时，在不确定性的范围内，一个新的超光速结出现了，其视速度为21 ± 2c。一般的多频行为的爆发可以解释的冲击波传播的框架内沿着螺旋路径在耀变体的喷流。
We present the results of optical (R band) photometric and polarimetric monitoring and Very Long Baseline Array (VLBA) imaging of the blazar S5 0716+714 along with Fermi γ-ray data during a multi-waveband outburst in 2011 October. We analyze total and polarized intensity images of the blazar obtained with the VLBA at 43 GHz during and after the outburst. Monotonic rotation of the linear polarization vector at a rate of ≳ 50° per night coincided with a sharp maximum in γ-ray and optical flux. At the same time, within the uncertainties, a new superluminal knot appeared with an apparent speed of 21 ± 2c. The general multi-frequency behavior of the outburst can be explained within the framework of a shock wave propagating along a helical path in the blazar's jet.
