Tracking Sunspots from Mars, April 2015 Animation

This single frame from a sequence of six images of an animation shows sunspots as viewed by NASA Curiosity Mars rover from April 4 to April 15, 2015. From Mars, the rover was in position to see the opposite side of the sun. The images were taken by the right-eye camera of Curiosity's Mast Camera (Mastcam), which has a 100-millimeter telephoto lens. The view on the left of each pair in this sequence has little processing other than calibration and putting north toward the top of each frame. The view on the right of each pair has been enhanced to make sunspots more visible. The apparent granularity throughout these enhanced images is an artifact of this processing. These sunspots seen in this sequence eventually produced two solar eruptions, one of which affected Earth. http://photojournal.jpl.nasa.gov/catalog/PIA19802
