Mars was favorably placed for telescopic observation in the northern hemisphere from January 1990 through March 1991. This report outlines the International Mars Patrol (IMP) observational programs of the Association of Lunar & Planetary Observers and summarizes the observations of the 1990-1991 Apparition. The Martian South Polar Region's seasonal aspects are described, the environmental conditions that favored the development and the movements of two individual dust storms during October and November 1990 are discussed. Although several reports on this apparition were presented previously to ALPO members at meetings and in popular astronomy magazines, a comprehensive report has not yet appeared in The Strolling Astronomer. Note: See Special reference list at the end of this article for previous papers pertaining to the 1990 apparition.
