Jet trajectory reconstruction in the ecliptic plane using the stereoscopic observations from both STEREO points of view. Left: jet reconstruction from EUVI 304 Å images taken between 0812 and 0916 UT. The reconstruction yields a strongly non-radial jet trajectory from the flare site toward the magnetic footpoints of both s/c with an estimated inclination angle of β = 63 ± 11° relative to the radial direction. δ = 34° and α = 22° are the longitudinal and footpoint separations between STEREO-A and STEREO-B, respectively. ϕ_A = 71° and ϕ_B = 58° are the angles between the s/c longitudes and their footpoints for STEREO-A and STEREO-B, respectively. The magnetic fields correspond to positive (green, outward arrow) and negative polarities (pink, inward arrow). Right: jet trajectory overplotted by PFSS open magnetic field lines.
