This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the narrow angle camera of NASA’s Voyager 2 spacecraft. The images were taken at a range of 7.1 million km (4.4 million miles) from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager’s cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen. Image credit: NASA / JPL.

Sketch of the relative positions of NASA’s and ESA’s spacecraft that observed the February 12, 2021 coronal mass ejections; ESA’s Solar Orbiter spacecraft was ‘behind’ the Sun from the perspective of Earth; the Earth was about 12 degrees west of Sun-center as seen from Solar Orbiter; ESA’s Proba-2, which orbits the Earth, and the ESA/NASA Solar and Heliospheric Observatory (SOHO), which is located in orbit around the Lagrange point 1, 1.5 million km in front of the Earth towards the Sun, also viewed the coronal mass ejection; NASA’s STEREO-A (Solar Terrestrial Relations Observatory) also caught a glimpse of the event from its viewpoint away from the direct Sun-Earth line; together the spacecraft provide valuable, different perspectives on the same event.
