An annular solar eclipse occurred on Sunday, June 21, 2020. An annular solar eclipse is a solar eclipse whose presentation looks like a ring, or annulus; it occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most, but not all, of the Sun's light. In this instance, the Moon's apparent diameter was 0.6% smaller than the Sun's.
