Eclipse caused by a syzygy of the sun moon and the Earth

Aristotle earth’s shadow has a circular shape as it moves across the moon

Use a lunar eclipse to estimate the distance of the moon and sun from the Earth

Eddington : Tested Albert Einstein theory of general relativity

Use DIY pinhole camera to track the progress of the moon across a projection off the sun’s surface and special solar viewing classes

Types

Totality

Total obscuration od the Sun

Hybrid

A combination of Annular and total eclipse

Partial

A misaligned obscuration of the sun

Phase 1 moon makes contact wit the sun

Phase 2 The moon makes second contact covers most of the sun

Phase 3

Corona is visible

Phase 4 moon makes 4 contact moving away

Phase 5 Final contact is made with the sun eclipse ends

Lunar Eclipse

IS when the Earth’s shadow is cast over the moon

Happens when Sun’s light passes through and the moon comes into contact with the red wavelengths and is refracted onto the Earth’s surface.

Partial Lunar Eclipses

During the partial phase, the sun, Earth and moon are not perfectly aligned

Earth shadows appears to take a bite out of the moon

Total Lunar Eclipse

Earth’s full Umbra shadow falls on the moon

The moon will be dark

Some light passing through the Earth’s atmosphere is scattered and refracted or bent and refocused on the moon, giving it a dim glow even in totality.

Penumbral lunar eclipse

Least interesting Moon in Earth’s outer shadowLikely unnoticeable as the moon in shaded by the Earth’s shadow

Solar Eclipse

Occurs when the moon and the sun and the earth syzygy

Total solar eclipse

Happens when the sun is completely blocked by the moon

Only visible from a specific part of the Earth

Moon is smaller and the shadow only passes through a narrow part of the Earth’s surface

Annular Eclipse:

When the moon does not cover the sun entirely of the sun even if the moon is completely centred in front of it

Happens when the Earth’s and the moon is closer to the Earth

Bright ring around the moon is the ring of fire.

Hybrid

A combination of a total and a annular eclipse

Starts from one type and becomes another.

Eclipse seasons

An approximate 35-day period during which it’s inevitable for at east two eclipses to take place

Two eclipses in one eclipse season

Two eclipse seasons in one year

Marks the start when lunar nodes point at the sun

Lunar Eclipse

The moon has to be above your horizon

Solar Eclipse

Nrrow track along the Earth’s surface

Accompanying partial ones can only be see next to that track

Solar Eclipse

Moon is close enough to the ecliptic plane during a new moon

During the eclipse season

Phase of a new moon

Moon gets between the Earth and the sun
