What is Lunar Eclipse Meaning?
Like any full moon, a lunar eclipse focuses your attention on relationships of all kinds. The September 16 lunar eclipse itself has a relationship to the previous moon phase, the September 1 solar eclipse. Projects started then can now be fine-tuned or completed, it is harvest time. However, this is a work in progress and will continue until the next series of eclipses in February 2017. The lunar eclipse can also be seen as an emotional adjustment, or compliment, to the themes of the solar eclipse.
As the Sun opposite Moon qualities of emotions and instincts reach their peak at a lunar eclipse so an objective and balanced look at personal relationships is possible. Being in touch with your own needs and intentions, and those of others, you can clearly see any relationship imbalances causing disharmony. With a lunar eclipse in particular, the blotting out of the Moon represents a resetting of emotions, clearing away the emotional baggage of the previous six months.
What is a Total Lunar Eclipse?
Eclipses of the Moon happen when the Sun, Earth and Moon are aligned to form an exact or an almost straight line. The technical term for this is syzygy, which comes from the Greek word for being paired together.

Earth’s Three Shadows
The Earth’s shadow can be divided into three parts:
- Penumbra – the outer part.
- Umbra – darker, central part.
- Antumbra – a partly shaded area beyond the umbra.
Sun, Earth and Moon Aligned
For a lunar eclipse to occur, the Sun, Earth and Moon must be roughly aligned in a straight line. If the Sun, Earth and Moon do not align, the Earth cannot cast a shadow on the Moon’s surface and an eclipse cannot happen.
When the Sun, Earth and Moon are not perfectly aligned, only the outer part of the Earth’s shadow covers the Moon. Such an eclipse is called a penumbral lunar eclipse. In a Total Lunar Eclipse, the Earth’s umbra completely covers the Moon.
The Earth’s umbra is about 870,000 miles (1.4 million km) wide.
Only at Full Moon
Total Lunar Eclipses happen only when:
- The Sun, Earth, and Moon are in a straight line.
- There is a full Moon.
Phases of the Moon
Full Moon and Total Lunar Eclipses
This is because the plane of the Moon’s orbital path around the Earth is inclined at an angle of 5° to the Earth’s orbital plane, also known as the ecliptic, around the Sun. The points where the 2 orbital planes meet are called lunar nodes. Eclipses can only take place near the lunar nodes and lunar eclipses occur when a full Moon happens near a lunar node.
The Moon Looks Red
What is Earthshine?
The Earth’s atmosphere removes or blocks parts of the sunlight’s spectrum leaving only the longer wavelengths. Because of this, a totally eclipsed Moon usually looks red.
Eclipses in Different Colors
A lunar eclipse can also be yellow, orange, or brown in color. This is because different types of dust particles and clouds in the Earth’s atmosphere allow different wavelengths to reach the surface of the Moon.
Seven Stages of the Eclipse
A Total Lunar Eclipse usually happens within a few hours. Totality can range anywhere from a few seconds to about 100 minutes. The July 26, 1953 Total Lunar Eclipse had one of the longest periods of totality in the 20th century – 100 minutes and 43 seconds.
There are seven stages of a Total Lunar Eclipse:
- Penumbral eclipse begins: This begins when the penumbral part of Earth’s shadow starts moving over the Moon. This phase is not easily seen by the naked eye.
- Partial eclipse begins: The Earth’s umbra starts covering the Moon, making the eclipse more visible.
- Total eclipse begins: Earth’s umbra completely covers the Moon and the Moon is red, brown or yellow in color.
- Maximum eclipse: This is the middle of the total eclipse.
- Total eclipse ends: At this stage, the Earth’s umbra starts moving away from the Moon’s surface.
- Partial eclipse ends: The Earth’s umbra completely leaves the Moon’s surface.
- Penumbral eclipse ends: At this point, the eclipse ends and the Earth’s shadow completely move away from the Moon.
