Longitude lineups between STEREO Ahead and Parker Solar Probe

This figure shows the difference in heliographic longitude between Parker Solar Probe and STEREO Ahead. The upper panel zooms in on when the two spacecraft are within 10 degrees of being radially aligned. The lower panel shows the heliocentric distance for Parker Solar Probe (solid) and STEREO Ahead (dot-dash). The dashed vertical lines mark the positions of the zero crossings in the upper panel. Many of these zero crossings occur close to Parker Solar Probe perihelia.
