Martian Dynamical Phenomena During June-November 1976: Viking Orbiter Imaging Results

A summary is presented of the orbital imaging observations of dynamical phenomena on Mars during the Viking primary mission. Clouds in the Tharsis/Amazonis regions are examined and the observation of an area of unusually high brightness to the southwest of Arsia Mons is considered. Attention is given to clouds and surface frost in the south polar region, the north polar cap, and aspects of dust storm activity.
