The analysis of polar jet responses using images from the LASCO C2 and STEREO COR 2 coronagraphs
Abstract
High cadence images taken by the X-Ray Telescope (XRT) onboard Hinode and the Solar Dynamics Observatory Atmospheric Imaging Assembly (AIA) instrument provide an opportunity to observe solar jetting activity. The brightest several of these polar jets show a positive correlation with high-speed responses traced into the interplanetary medium, and have been reported in the full SMEI (Solar Mass Ejection Imager) data set images at large solar distances in the heliosphere where they retain a semblance of their original identity. LASCO C2 and STEREO COR 2 coronagraph images allow measurements of the coronal response to some of these jets, and the nearby background solar wind velocity, giving a determination of their speeds and energies that we can compare with Hinode and AIA observations. In this preliminary study we document two of these solar jet traversals into the inner heliosphere in the region intermediate to this region and the XRT and AIA observations.
