2 TYPES OF ECLIPSES:
• SOLAR ECLIPSE• LUNAR ECLIPSE
SOLAR ECLIPSES• Solar Eclipse- caused by the
moon making a small shadow on the Earth.– Moon crosses in front of
the sun.– Moon is in a new moon
position.– Only a small number of
people can see a solar eclipse.
– Occurs during the day.
Recent Solar Eclipse
• September 13, 2015, a partial eclipse that was visible in Africa and Antarctica.
Types of Solar Eclipses:
1. A partial solar eclipse occurs when only part of the Sun is covered by the Moon which appears to take a “bite” out of the Sun.
Types of Solar Eclipses:
2. Annular eclipse occurs when the Sun’s center is covered by the moon , leaving its edges left uncovered, producing a ring (or annulus) of the Sun around its edges.
Types of Solar Eclipses:
3. A total solar eclipse takes place when the Sun becomes completely covered by the moon.
Types of Solar Eclipses:
4. A hybrid eclipse is one which is seen as annular by observers in one part of the Earth, and at the same time, is seen as a total eclipse by others in another part of the Earth.

SOLAR ECLIPSE
• There are two parts to the shadow.– Umbra- darkest part– Penumbra- lighter part
• Those people standing in the umbra see a total solar eclipse.
• Those people in the penumbra see a partial solar eclipse.

FUTURE SOLAR ECLIPSES• Total solar eclipse -Indonesia including Sumatra,
Borneo, and Sulawesi, and from locations in the Pacific Ocean.
• Northern and eastern Australia, in South Asia, and in East Asia will be able to see a partial eclipse.
• The eclipse will begin at 23:19 UTC on March 8, 2016, and its maximum point will take place at 01:59 on March 9, 2016. Totality will last for 4 minutes and 9 seconds.
Future Solar Eclipses
• March 9, 2016. -Asia and Australia. • September 1, 2016 Africa and parts of the Indian
Ocean. • February 26, 2017 South America, Africa and
Antarctica. • The next solar eclipse that can be seen in the
United States and North America will be on August 21, 2017.
LUNAR ECLIPSE
• Lunar eclipse- caused by the earth’s shadow covering the moon.– Moon is in a full moon
position.– Large numbers of people
can see.– Occurs at night.
LUNAR ECLIPSE
• There are two parts to the shadow- umbra and penumbra.– When the moon is in
the umbra a total lunar eclipse occurs.
– When the moon is in the penumbra a partial lunar eclipse occurs.
3 Types of Lunar Eclipses
• Total Lunar Eclipse-Earth’s full (umbral) shadow falls on the moon.
• Partial Lunar Eclipse-the sun, Earth and moon are not quite perfectly aligned, and Earth’s shadow appears to take a bite out of the moon.
• Penumbral Lunar Eclipse-the moon is in Earth’s faint outer (penumbral) shadow.

LUNAR EXCLIPSE 2015
• September 27, 2015- US, Canada, and Central and South America, this rare Total Lunar Eclipse of a Supermoon.
• September 28, 2015- Europe, South/East Asia, Africa, the Arctic, and in the Pacific, Atlantic, and Indian Oceans it starts after midnight on.
• Also called a Blood Moon this eclipse lasted for about 1 hour and 12 minutes.
Future Lunar Eclipses
• March 23, 2016: Penumbral eclipse. Visible from Asia, Australia, Pacific Ocean, western Americas.
• Sept. 16, 2016: Penumbral eclipse. Visible from Europe, Africa, Asia, Australia, western Pacific Ocean
Blood Red Moon-
-Earth's atmosphere -Amount of dust and clouds in the moon’s atmosphere.-extra particles from a recent volcanic eruption on the moon.

Lunar Eclipse 2008
TRIVIA:
• A solar eclipse always occurs two weeks before or after a lunar eclipse.
• Lunar eclipses can occur up to three times a year.• Solar eclipses always occur between two and five
times a year. Often, these eclipses are unnoticed because they only pass over a small portion of the earth.
TRIVIA:
• The longest duration for a solar eclipse is seven and a half minutes.
• The element helium was discovered during a solar eclipse in 1868. French scientist Pierre Janssen noticed a peculiar yellow line, with a wavelength of 587.49 nanometers, while looking at the sun during an eclipse.
TRIVIA• On May 29, 1919, observations recorded during
a total eclipse of the sun helped prove Albert Einstein’s theory of relativity.
• On May 28, 585 B.C.E., an eclipse halted a battle between the Medes and the Lydians in present-day Turkey. Both sides believed the eclipse was a bad omen and immediately stopped fighting!
