Why is the total solar eclipse observing belt ring shaped

Because the observer is in the shadow of the Moon (in the eclipse zone) when the Moon casts a shadow on the Earth, the Moon will completely or partially obscure the Sun.

If the Moon's orbit is circular and slightly closer to the Earth, and if it is also in the same orbital plane, then we will see a total solar eclipse from the Earth every time a new moon occurs. However, because the Moon's orbit is more than 5 degrees oblique to the Earth's orbit around the Sun, the Moon's shadow usually misses the Earth. A solar eclipse can only occur if the Moon is close enough to the ecliptic plane during the New Moon.

There must be a special case for both events, since the Moon's orbit crosses the ecliptic twice at its orbital node in each node month (day), while the new moon can occur only once per synodic month (day). As a result, solar (and lunar eclipses) occur only during the season of solar eclipses, at least twice a year, and only a maximum of 5 solar eclipses; Among them, there are generally no more than two total solar eclipses.

Total solar eclipse observation report 1, observation activity content 1A total solar eclipse measures the time of four contacts between the edge of the Moon and the edge of the Sun (i.e., the first eclipse, the eclipse, the light, and the round). Name Initial Loss Eating Both Raw Light Rounding Time 8:

59 Time difference 73 minutes 5 minutes 80 minutes Observation report: The time from the beginning of the partial solar eclipse to the total solar eclipse phase is about the same as the time from the total solar eclipse phase to the full circle, while the time period of the total solar eclipse is relatively short. 2.

Observation of the corona. The corona is the outer atmosphere of the Sun that is only revealed during a total solar eclipse. The shape, size, and structure of the corona seen during each total solar eclipse varies.

Observations can be recorded using the drawing method. 3.Observe Bailey beads and diamond rings on the surface of the Moon.

Both the Bailey Bead and the Diamond Ring occur just before and after the eclipse and after the light is born, so you can keep an eye out for it at this time. 4.Observation of meteorological changes.

During a total solar eclipse, the temperature drops rapidly because the sunlight suddenly disappears, and the temperature change can be recorded with a simple thermometer. Time 8:00 8:30 9:30 10:10:30 11:30 11:30 Temperature ( )36 37 36 32 35 36 Observation report: In the event of a partial solar eclipse, the temperature does not change much, and once the total eclipse stage is reached, the temperature plummets by about 5, which shows that the total solar eclipse still has a certain impact on the temperature at that time.

5.Observation of the image of the small hole. Small hole shape Circle Triangle Larger circle Text image result The pattern is round, and the shape of the image is in the same direction as the partial solar eclipse.

However, it is more vague and the pattern is round, and the shape of the image is consistent with the direction of the partial solar eclipse. And the number of images is the same as the number of holes. 6.

Take a look at the astronomical charts presented in the book beforehand and observe celestial objects that cannot be observed on a normal day during a total solar eclipse. Observations: During the total solar eclipse, the brightness of the sky decreases, and there are brighter stars around the sun.

The part that can be seen in an annular solar eclipse is the edge of the sun, and the part that is obscured is the vast majority of the sun except the edge.

The entire sun is obscured by a total solar eclipse, and the Clan Digger can only see a circle of light around the sun.

An annular solar eclipse is a type of solar eclipse. It occurs when the central part of the sun is dark and the edges are still bright, forming a halo. This is because the Moon is between the Sun and the Earth, but it is far away from the Earth and cannot completely cover the Sun.

During an annular solar eclipse, the projections of objects sometimes overlap and overlap. Sanzheng.

A total solar eclipse is a type of solar eclipse, an astronomical phenomenon in which the sun's rays are completely obscured by the moon in parts of the Earth. Total solar eclipses are divided into five stages: initial loss, eclipse, eclipse, regeneration, and recovery. Since the Moon is smaller than the Earth, only people in the moon's umbra can see a total solar eclipse megahigh.

Folks call this phenomenon the Tengu Eclipse Day.

The Moon is a phenomenon in which the Moon is between the Earth and the Sun, forming a shadow on the Earth.

The shadow of the moon can be divided into three parts: umbra, penumbra, and pseudoumbra. The orbit of the Moon around the Earth and the orbit of the Earth around the Sun are not perfectly circular, so the distance between the Sun and the Moon and the Earth is sometimes close and sometimes far. Therefore, during a solar eclipse, the observer sees the Sun in its entirety obscured by the Moon in the umbra range, which is called a total solar eclipse; The observer sees in the penumbra that the Sun is partially obscured by the Moon, which is called a partial solar eclipse; The observer sees the middle part of the Sun obscured by the Moon in the pseudoumbra, which is called a partial solar eclipse; There is a halo left around the perimeter, which is called an annular solar eclipse.

When the Moon orbits the Earth until the Sun rises and sets almost at the same time as the Sun and the Earth, the Moon cannot be seen from the Earth, which is called the New Year, and the solar eclipse phenomenon occurs at the New Year. The cycle of the new is about a few days. But not every other day, a solar eclipse occurs because the plane of the Moon's orbit around the Earth and the plane of the Earth's orbit around the Sun do not coincide exactly, with 5°9 in between'The average angle.

Therefore, a solar eclipse occurs only when the Sun is within a certain angle of the intersection of the two orbital planes.

1. Special eclipse glasses.

When watching a solar eclipse, wear glasses that are designed to observe the sun, and ordinary sunglasses or sunglasses can only be used to observe the scenery in the sun, and must not be used to look directly at the sun, because they cannot block ultraviolet rays.

2. Make a pinhole projection box.

You can use a 1 to 2 meter long cardboard box, with a hole of about 10 cm in the center of each end, and the upper end of the hole with tin foil is pasted with a disadvantage, and then a needle is used to pierce a pinhole in the center of the tin foil. The other end is covered with white translucent paper, and then tested under the sun to see if the sun can be created on the translucent paper. It should be noted that the sun cannot be directly observed through the pinhole with the naked eye, otherwise it will also burn the eyes.

3. Welding goggles.

Welding goggles for electric welding, because welding goggles are one of the best tools for observing solar eclipses.

4. A camera with a filter.

Look with a camera, but be sure to have a filter, viewing the eclipse directly from the frame can also hurt the eyes.

5. Telescope projection.

After installing the Bard membrane, the solar eclipse is projected through a telescope, and the telescope cannot be used directly, otherwise it will burn or discredit the eyes, and in severe cases, it may lead to blindness.
