The Antananarivo close encounter wave is one of the best-known African UFO cases of the 1950s. Usually dated to 16 August 1954, it became famous because a strange green luminous object and a larger metallic-looking craft were reportedly seen by large numbers of witnesses over Antananarivo at low altitude, with power failures, animal panic, and a second related observation farther north soon afterward.

The Río Cuarto close encounter wave refers to the cluster of UFO reports that drew national attention to Río Cuarto, Córdoba, in January 2008. The wave became famous because a luminous object was reportedly seen by an airport operator and hundreds of residents, triggered Air Force inquiries and talk of outside technical assistance, and then fed into a broader local belief that southern Córdoba is one of Argentina’s recurring UFO zones.

The Canary Islands close encounter wave refers to a series of dramatic UFO reports centered on the Spanish Canary Islands in the 1970s, especially the famous 22 June 1976 mass sighting and related military-observed events. The wave became one of Spain’s best-known UFO clusters because it combined hundreds of witnesses, sea-and-air observations, declassified official files, and later arguments that at least some of the spectacular displays were caused by missile launches rather than alien craft.
