What is the phase of the moon corresponding to the time when the total solar eclipse occurs?

I'm dizzy, what I said upstairs in front of me is right, but the moment the total solar eclipse occurs, the shadow of the moon hits the earth, and when this period of time passes, there is nothing blocking the moon, and the moon seen on the earth at this time should be a full moon. Moreover, according to many years of observational data, the total solar eclipse occurs around the fifteenth day of the lunar calendar, and the moon phase at this time is also a full moon.

A total solar eclipse occurs when the Sun, Moon, and Earth are on the same straight line, and both the Moon and Sun are on the same side of the Earth, so that the Moon's shadow falls on the Earth. The moon phase at this time is the new moon.

The eclipse must have occurred on the first day of the lunar calendar. At this time, the Moon is located between the Earth and the Sun, but because the orbit of the Sun (ecliptic) and the orbit of the Moon (White Path) are at an angle of 5°9, not every new day there is a solar eclipse, and when a solar eclipse occurs, both the Sun and the Moon must be near the "yellow and white node" (ascending or descending node).

A solar and lunar eclipse must occur within a certain boundary of the yellow and white nodes of the new moon and the full moon, which is called the "eclipse limit". Calculations show that for a solar eclipse, a solar eclipse can occur if the crescent moon is within about 18 degrees near the intersection of the ecliptic and white paths; If the crescent moon is within about 16 degrees near the intersection of the ecliptic and white paths, there must be a solar eclipse.

During a lunar eclipse, the direction of the Sun and the Moon is 180° different from each other for the Earth, so the lunar eclipse must have occurred around the 15th day of the lunar calendar.

A total lunar eclipse occurs when the entire Moon enters the Earth's umbra. The moon phase is a full moon (looking at the sun, around the night of the 15th or 16th day of the lunar calendar): 180 degrees;

The sun and moon are on the same side during the eclipse, so it is "Shuo", that is, a new moon; During a lunar eclipse, the Sun and Moon are on either side of the Earth, which is the "Wang", that is, the full moon. Because when the moon is full, the position of the moon, the earth, and the sun is: the moon - the earth - the sun.

When the sunlight is blocked by the earth, the moon enters the shadow of the earth, because the moon can no longer reflect the sun's light, there is no light to enter the human eye, and people see the lunar eclipse.

Because at the time of the new moon, the position of the moon, the earth, and the sun is: the earth-moon-sun. When the sun's light is blocked by the moon, people see that the sun is blocked by the moon. i.e. a solar eclipse.

The shape of the notch in the moon phase is different from that of the moon in the eclipse chart. If it is because "the earth blocks the sun's rays", then there should be a shadow in the shape of the earth on the moon, the earth is spherical, and the shadow is of course round, so when the eclipse occurs, the missing part of the moon is round. However, in the change of moon phases, the missing part of the moon is not round, and looks more like a half-light and half-dark ball turning.

The moon itself does not emit light, it is all illuminated by the sun, and the sun can only illuminate half of the moon, and the moon revolves around the earth, so when the moon turns to different positions around the earth, it will turn different proportions of the bright side towards the earth.

There are three types of lunar eclipses: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses. A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra; And when the entire Moon enters the Earth's umbra, a total lunar eclipse occurs. As for the penumbral lunar eclipse, it means that the moon only passes over the penumbra of the earth, causing a very slight decrease in the brightness of the lunar surface, which is difficult to see with the naked eye, so it is not noticed.

Answer B This question is based on astronomical phenomena to examine the cause and distribution of the moon phase, the lunar eclipse occurs in the sun, the earth, and the moon are collinear, and the earth is located between the sun and the moon, so the moon at this time is correspondingly a full moon, so choose item B.

The process of a total solar and lunar eclipse and annular solar eclipse can include the following five periods: the first loss, the eclipse, the eclipse, the light, and the reunion.

There are only three periods in a partial eclipse of the sun and moon: the first loss, the eclipse and the reunion;

The process of lunar eclipse: The process of lunar eclipse is divided into five stages: initial loss, eclipse, eclipse, light, and roundness. First loss:

The Moon has just touched the Earth's umbra, marking the beginning of the lunar eclipse. Eclipse: The western edge of the Moon is inscribed with the western edge of the Earth's umbra, and the Moon just enters the Earth's umbra.

Eclipse: The center of the Moon is closest to the center of the Earth's umbra. Shine:

The eastern edge of the Moon is intangent to the eastern edge of the Earth's umbra, at which point the total eclipse phase ends. Round: The western edge of the Moon is tangent to the eastern edge of the Earth's umbra, and the lunar eclipse ends with Zheng Cheng in his hands.

The course of the eclipse:

First eclipse: Since the Moon orbits the Earth from west to east, the eclipse always begins at the western edge of the Sun's circle. When the eastern edge of the moon first touches the circular surface of the sun (that is, the moment when the eastern edge of the lunar surface and the western edge of the lunar surface are tangent), it is called the first wancing.

The first waning is the moment when the eclipse process begins. Eclipse: From the beginning of the loss, it is the partial eclipse stage.

As the moon continues to move eastward, the part of the sun's circle that is obscured by the moon gradually increases, and the intensity and heat of sunlight decrease significantly. When the eastern edge of the lunar surface is intangent to the eastern edge of the solar surface, it is called an eclipse. The entire circle of the sun is obscured at this time, so the eclipse is the moment when the total solar eclipse begins.

Eclipse: After the eclipse of the moon, the moon wheel continues to move eastward, and when the center of the moon wheel and the center of the sun are closest to each other, it reaches the eclipse of the solar eclipse, which is the time when the sun is obscured by the moon the most.

Generating light: The moon continues to move eastward, and the moment when the western edge of the lunar surface and the western edge of the solar surface are intangent is called shengguang, which is the moment when the total solar eclipse ends.

Roundness: After the light is generated, the moon surface continues to move away from the sun surface, and the part of the sun that is obscured gradually decreases, when the western edge of the moon surface tangent to the eastern edge of the sun surface, it is called a double circle.

Of course, we now have astronomical data that can accurately calculate the solar and lunar eclipses in hundreds of years and the regions that can be observed.

A solar eclipse, also known as a solar eclipse, is the movement of the moon between the sun and the earth, if the three are exactly in a straight line, the moon will block the light of the sun to the earth, and the black shadow behind the moon falls on the earth, and the solar eclipse phenomenon occurs.

A total solar eclipse occurs only when the Moon is at perigee, when the moon's umbral cone is longer than the distance between the Moon and the Earth, so that the umbral cone can sweep to the Earth's surface.

Since the actual volume of the Sun is much larger than that of the Moon, total solar eclipses are usually only visible in a very small area of the Earth, because the Moon's umbra is only a small dot to the Sun. The last total solar eclipse occurred on March 20, 2015.

A total annular eclipse occurs only when the Earth's surface is very close to the tip of the moon's umbra, or the distance between the Moon and the Earth's surface is very close to the length of the moon's umbra.

The eclipse is the first day of the new month, and it is the new moon; The time of the lunar eclipse is the fifteenth and it is a full moon.
