Solar eclipse of May 30, 1984
20th-century annular solar eclipse
An annular solar eclipse occurred on Wednesday, May 30, 1984. 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. Annularity was visible in Mexico, the United States, Azores Islands, Morocco and Algeria. It was the first annular solar eclipse visible in the US in 33 years. The Moon's apparent diameter was near the average diameter because it occurred 6.7 days after apogee (apogee on May 24, 1984, at 01:00 UTC) and 7.8 days before perigee (perigee on June 7, 1984, at 11:15 UTC).
