The annular solar eclipse of February 26, 2017 was observed almost exclusively in the southern hemisphere. Chile , Argentina , Angola and the Democratic Republic of the Congo were in the zone of annular eclipse. The eclipse began 3100 kilometers west of the Chilean coast in the Pacific , covered South America , the southern Atlantic and ended in southwest Africa .
At the middle of the eclipse the moon covered the sun to more than 99 percent. The remaining, narrow ring of the sun could already be broken up into individual fragments due to the unevenness of the lunar landscape. The duration of the annular phase during the largest eclipse by the moon was 44 seconds on the central line.
In ring-shaped eclipses, in which the moon almost covers the sun at the time of the greatest eclipse and whose maximum duration is less than 2 minutes and 18 seconds, the maximum duration of the ring-shaped phase is not during the time of the greatest eclipse, but on the central line at the beginning or end of darkness. In this eclipse, the maximum duration of the ring-shaped phase was actually theoretically 1 minute and 22 seconds and was at the very beginning of the eclipse, it steadily decreased until the time of the greatest eclipse and then increased again.
