màxim Annular Eclipse of the Sun, 26/02/2017
In a narrow corridor cutting across the southern reaches of Chile and Argentina, and stretching across the Atlantic to Angola, the Democratic Republic of the Congo, and Zambia in Africa, the Moon crossed the sun dead-center. Yet it only covered 99% of the solar disk. ( A video illustration of the path of the eclipse)
