Rapid Rotation of an Erupting Prominence and the Associated Coronal Mass Ejection on 13 May 2013

In this paper, we report the multiwavelength observations of an erupting prominence and associated CME on 13 May 2013. The event occurs behind western limb in field view SDO/AIA. is supported by a highly twisted magnetic flux rope shows rapid rotation counterclockwise direction during rising motion. lasts for $\sim$47 minutes. average period, angular speed, linear speed are $\sim$806 s, $\sim$0.46 rad min$^{-1}$, $\sim$355 km s$^{-1}$, respectively. total twist angle reaches $\sim$7$\pi$, which considerably larger than threshold kink instability. Writhing motion 17:42$-$17:46 UT clearly observed SWAP 174 {\AA} EUVI board STEREO spacecraft 304 after reaching apparent height $\sim$405\,Mm. Therefore, eruption most probably triggered A pair conjugate flare ribbons post-flare loops created STA/EUVI. onset time writhing consistent with commencement impulsive phase related flare. 3D morphology positions derived using graduated cylindrical shell (GCS) modeling. kinetic evolution reconstructed divided into slow-rise ($\sim$330 s$^{-1}$) fast-rise ($\sim$1005 edge-on width constant (60$^{\circ}$), while face-on increases from 96$^{\circ}$ to 114$^{\circ}$, indicating lateral expansion. latitude source region decreases slightly $\sim$18$^{\circ}$ $\sim$13$^{\circ}$, implying equatorward deflection propagation.
