Solar eclipse of May 30, 1984

An annular solar eclipse occurred at the Moon's ascending node of orbit on Wednesday, May 30, 1984, with a magnitude of 0.998. 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 (on May 24, 1984, at 01:00 UTC) and 7.8 days before perigee (perigee on June 7, 1984, at 11:15 UTC).

Observations
During this eclipse, the apex of the moon's umbral cone was very close to the Earth's surface, and the magnitude was very large. The edges of the moon and the sun were very close to each other as seen from the Earth. Images of the chromosphere and Baily's beads on the lunar limb, which are usually only visible during a total solar eclipse, could also be taken. A team of the University of Florida took images, about half of which being those of the chromosphere and the other half the photosphere, in Greenville, South Carolina. Jay Pasachoff led a team from Williams College, Massachusetts to Picayune, Mississippi.
