What is the position and time of seeing the moon in the morning and evening?

One word to remember:

Up up, up west, down down, east east.

Meaning: the first quarter moon is in the western sky in the first half of the first half of the lunar month, and the west side of the moon is bright;

The second quarter moon is in the eastern sky in the second half of the second half of the lunar month, and the east side of the moon is bright.

The first floor of the friend is not enough).

The attached picture is a month-over-the-month change in the phases of the moon:

Upper up West West, lower down East East: It means that the first half of the first half of the moon is in the western sky, and the west side of the moon is bright; In the second half of the second half of the moon, the eastern sky is bright, and the eastern side of the moon is bright.

The moon shines because it shines on the sun, and in the morning and evening, when the sun sets (or rises) and the moon rises (or sets), a small error is formed. That is, when the sun shines on the earth, the moon is just about to leave or is about to come, and then it shines a little bit of the moon itself, and the moon becomes visible.

When the Moon is far away from the Sun, the Moon can only be seen in the night sky. If the Moon is not too far away or too close to the Sun, i.e. on those days before or after the first or second quarter, the Moon will appear in the sky at the same time as the Sun in broad daylight, sometimes to the east of the Sun, sometimes to the west of the Sun.

Orbital motion

1. Revolution. The Moon orbits the Earth in a circular orbit. The great circle of this orbital plane on the celestial sphere is called the "white path". The plane of the white channel does not coincide with the celestial equator, nor is it parallel to the plane of the ecliptic, and the spatial position is constantly changing.

Cycle day. The average inclination of the lunar orbit (white path) to the Earth's orbit (ecliptic) is 5°09. But it is known that the Moon is gradually departing from the Earth at an average rate every year.

2. Rotation. The Moon rotates while revolving around the Earth, and the period day is exactly a sidereal month, so we can't see the far side of the Moon. This phenomenon is called "synchronous rotation", or "tide locking", and is almost a universal law in the world of solar system satellites. It is thought to be the result of the long-term tidal action of satellites on planets.

The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon.

During the day, the sky is bright because the atmosphere scatters sunlight. But the Moon is close enough to Earth and large enough that it can also reflect some of the sunlight and appear brighter than the surrounding sky, allowing people to see it during the day. ”

The second half of the lunar calendar is the last quarter moon, and the moon's rise and setting are delayed.

That is, the moon had not yet set at dawn.

Therefore, there will be the phenomenon of menstruation.

It is normal for the moon to rise in the east and set in the west like the sun, and it is not unusual to see the moon in the west after sunset, because the moon is about to go down with the sun, but it has not yet gone down.

So you can speculate from this that the sun must not have risen a little earlier than the moon in the morning of the day, the problem is that the sky is already very bright when the sun rises, and most people are not in the habit of looking for the moon during the day, so not many people notice the moon rising during the day. It was only after the sun had gone down and it was dark that we noticed the moon following the sun, and it was ready to go down.

So, never make the mistake of thinking that the moon is rising in the west, if you keep observing for a few minutes, you will see that the moon is sinking to the west, not rising. It's even better if there are buildings nearby, and you can use them as a reference to see that the moon is sinking.

Normally, today is the twenty-eighth day of the lunar calendar, and the moon is about 30° west of the sun. It is located high in the east after sunrise, and if the weather permits, the air quality is relatively good, and it is not difficult to see the moon after sunrise.

If you pay attention to the sky, it can be said that it is commonplace to see the moon during the day, the lunar calendar is 29 or 30 days, and in the city, from the fourth to the fourteenth day of the lunar month, the moon can be found before sunset; From the eighteenth to the twenty-eighth of the lunar calendar, the moon can be found after sunrise.

As for some people calling it "the sun and the moon shine together", and even titled it "rare", "wonder", and "once in x years", it can only be said that it is rare and strange.

Are you talking about the moon appearing during the day? Because the moon is bright enough, and the stars are sometimes bright enough (Venus in the morning and evening), they are not obliterated by the sun's brilliance. It is said that once there was a comet that was bright enough to be seen during the day.

In fact, the other stars were there during the day, but they were not bright enough to be seen by my door. It's the same as in a rural area where there are no lights, but in a city where the street lights are bright, we can only see a few stars.

The moon can be seen during the day because the sun is less bright when this stool is combined. Split grandson

The blue sky cannot cover the brightness of the moon, or the cycle of the earth's rotation around the sun is different from the cycle of the moon's rotation around the earth, so that the sun and the moon shine together, and the shape of the moon will constantly change in a month's time.

1. The brightness is different.

During the day, you can see the moon in the finch pants, probably because of the different brightness. In the early morning or evening, when the sun is rising or setting, the brightness of the land is low, and the blue sky cannot cover the moon, so the moon is seen during the day.

2. The sun and the moon shine together.

The moon can be seen during the day, which may be a phenomenon of the sun and moon shining together. The period of the Earth's rotation around the Sun is one year, while the period of the Moon's rotation around the Earth is two acres and 17 days.

3. Moon shape.

The shape of the moon changes over the course of a month. In the lunar calendar, the moon on the first day of the new year is a thin line, from the second day to the beginning of the new year.

The moon from the sixth and twenty-fourth to the end of the month is like a curved eyebrow, and the beginning of the seventh month.

The moon on the eighth and twenty-third is semicircular, and the ninth moon arrives.

Ten. 4. The moon from 17 to 22 is elliptical, and the lunar calendar.

Ten. The moon of the fifth and sixteenth months is shaped like a disk.
