An annular
solar eclipse will occur on June 21, 2039. 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. This eclipse will start only a few hours after the
northern solstice and most of the path will go across areas with
midnight sun. For mainland
Norway and
Sweden it will be the first central solar eclipse since
June 1954.
