Solar eclipse of February 26, 2017
Introduction An annular solar eclipse took place on February 26, 2017.A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring only 4.7 days before perigee (Perigee on March 3, 2017), the Moon's apparent diameter was larger. The moon's apparent diameter was just over 0.7% smaller than the Sun's.It was visible across southern South America in the morning and ended in south-western Africa at sunset. In Argentina, the best places to see the eclipse were located in the south of the Chubut Province, in the towns of Facundo, Sarmiento and Camarones. Lunar perigee occurred at about 2017 Mar 03 at 07:41:24.5 UTC, 4.7 days later.
