Ulysses Orbit Projected on Solar Disk

The image shows the orbit of Ulysses projected on to the solar disk as seen from Earth. The vertical line joins the north and south ecliptic pole. Symbols are plotted for the first day of each calendar month, and open circles mark positions on the visible disk. At latitudes below ~50 degrees, the ecliptic longitude of the spacecraft is within 90 degrees of the Sun-Earth line for 6 months of each year, typically between January and June.
