SOLAR & LUNAR ECLIPSES
ECLIPSES -- Reference: 'American Ephemeris for the 21st Century'
SOLAR ECLIPSES (occur at new moons)
Partial ..Where the moon does not completely cover the solar disk.
Total .. Where the moon completely covers the solar disk as seen from a shadow path on the earth's surface.
Annular .. A 'total', but the moon is too far from the earth for the apex of its shadow to reach the earth's surface. Therefore the moon will not entirely hide the sun and a narrow ring of light will surround the dark new moon.
LUNAR ECLIPSES (occur at full moons)
Appulse .. A penumbral eclipse where the moon enters only the penumbra of the earth.
Partial .. Where the moon enters the umbra without being totally immersed in it.
Total .. Where the moon is entirely immersed within the umbra.
