1. The movements of the Earth, moon, and sun affect how moon appears from the Earth. Occasionally, the Earth or moon may block the sun’s light. This produce what we call
ECLIPSES
IPLSEECS
A shadow is made up of a dark, small inner shadow called umbra and a lighter, large outer shadow called penumbra.

4. PERIGEE
The point of the moon’s orbit closest to the Earth. ( km away)
APOGEE
The point of the moon’s orbit farthest from Earth. ( km away)
ALBEDO
– characteristic wherein the moon does not give off its own light, it only reflects light from the sun.

6. PHASES OF THE MOON

7. Lunar Eclipses
The Earth moves between the Sun and the Moon, blocking the Sun’s light, and causing the moon to glow red.
Occurs during full moon.

8. Types of Lunar Eclipses
Total Lunar Eclipse
Partial Lunar Eclipse
Penumbral Lunar Eclipse

9. TOTAL LUNAR ECLIPSE – when the Moon passes completely into the Umbra, or total shadow of the Earth.

10. The Total Lunar Eclipse of Dec. 21, 2010 was widely seen from the USA.

11. PARTIAL LUNAR ECLIPSE – Occur when the Moon does not fully move into the Umbra

13. PENUMBRAL LUNAR ECLIPSE – When the moon passes only through the penumbra, or partial shadow. They are barely visible.

16. SOLAR ECLIPSE
Occurs when the Moon travels between the Sun and the Earth and comes directly between the two during day.
Occurs during New Moon.

17. Types of Solar Eclipses
Total Solar Eclipse
Partial Solar Eclipse
Annular Solar Eclipse

18. TOTAL SOLAR ECLIPSE – can only occur if you are at the exact spot within the moon’s umbra (which isn’t very big).

19. Total solar eclipse as viewed from Australia

20. PARTIAL SOLAR ECLIPSE – Visible if you are in the penumbra of the shadow. Only some of the moon will be shadowed.

21. Partial solar eclipse, about 10-20%

22. ANNULAR ECLIPSE – occurs when the moon and the sun are exactly in the same line but the moon is farthest from the Earth in its orbit. This makes the moon look smaller, so during the eclipse you see an outer ring of light from the Sun.

24. What part of the Sun is visible around the edges of the moon?
CORONA
Also, are seeing the dark side of the moon.

25. The DIAMOND RING EFFECT is a visual phenomenon that occurs during a TOTAL SOLAR ECLIPSE. It is seen from earth when standing in the umbra of the moon’s shadow, and occurs as a part of Baily’s Beads. Baily’s Beads are glimmers of the sun’s brilliant surface which shine as dots of light around the disc of the lunar shadow. When only one “bead” remains, momentarily
