Abstract: Jets are seen on the Sun at all scales - from those occurring in coronal holes to those in active regions. The process of creating jets is often thought to be related to reconnection between open and closed field lines. Active region (AR) jets occur regularly at small-scale, but can occur on a larger scale related to CMEs and SEPs. Understanding the process of jets requires spectral and imaging data across different energy regimes. On August 25, 2011, a series of jets occurred at the edge of an active region, located near the western limb. We choose this example as it was observed with both SWAP (replicating EUI on Solar Orbiter) and Hinode/EIS (replicating SPICE on Solar Orbiter), radio data (replicating RPW on solar orbiter). The recurrent jets on August 25, 2011, were associated with type III radio bursts. Our aim was to determine why the jets occur in this particular active region, what the dynamics are, and if we can predict what we might see with Solar Orbiter. In the radio triangulation study of type III radio bursts associated with jets, we employed goniopolarimetric measurements taken simultaneously from STEREO A and WIND spacecraft. The reconstructed propagation paths of the interplanetary type III bursts associated with jets indicate that the fast electron beams are propagating towards the Earth, but the path does not completely coincide with the Parker spiral. This deviation in the propagation path of the electron beams associated with jets is probably due to the influence of a nearby coronal hole.
