This false-color Envisat image, acquired on June 6, 2010,
highlights a unique cloud formation south of the Canary Island archipelago, some
95 km from the northwest coast of Africa (right) in the Atlantic Ocean. Seven
larger islands and a few smaller ones make up the Canaries; the larger islands
are (left to right): El Hierro, La Palma, La Gomera, Tenerife, Gran Canaria,
Fuerteventura and Lanzarote.
