Phenomenon forecast

Lili Qiu -Summer Summer

sun

Run from Cancer to Leo. At present, the solar is not strong, and there are several small sunspots on the front, which can be observed by a telescope with light reduction.

moon

On August 12 (July 15th of the lunar calendar, Zhongyuan Festival) at 9:36, the full moon time was about 361,000 kilometers from the earth, and it was visible all night.

Mercury

Star, from Leo to the room of the room. The angle distance from the sun continues to increase, but it is still difficult to observe.

Venus

From Gemini to Cancer. The angle distance from the sun continues to decrease. As a low altitude appearing in the northeast as the "Star Star", it can be observed with the naked eye.

Mars

From Aries to Taurus, it rises around 1 am, and can be observed before dawn in the middle of the night.

Jupiter

Rebellion in the whale seat. It rises around 9 o'clock at night, and can be observed before dawn in the middle of the night.

Saturn

Saturn on August 15th. At night, it rises from the southeast and can be observed all night.

Meteor shower

At 9:00 to 10:00 on August 13, the Yingxian meteor shower ushered in great. At 21:00 on the 12th and 13th, the radiation point rises until the day after dawn. However, due to the serious influence of the brightness of the background of the full moon, the dull meteor in the group will be missed.

tips

Meteor is a phenomenon of glowing and heat after the meteor body in the solar system breaks into the earth at the high speed. When a large number of meteor bodies with similar tracks enter the earth's atmosphere within a short time interval, a meteor shower is formed. Due to the perspective effect, when the internal meteor in the original orbit was almost parallel entered the atmosphere, it looked like a point that shot from the ground. This point is called the radiation point of the meteor shower, and according to the constellation of the radiation point, the constellation point is located. Or nearby stars come to name meteor shower.

The mother of the meteor rain is mainly comet. Comets are constantly "erupting" comet dust scattered on its orbit to form a dust group (meteor group). When the earth is close to different dust group tracks, there will be corresponding meteor showers. The mother of the Yingxian Meteor Shower comes from Comet of Swift Tattel (109P/SWIFT-TUTTLE). This is a periodic comet. Every time you return, a new meteor body will be left on the track. From mid -July to late August each year, the earth will pass through the orbit of these meteors. The meteors in the group impact the earth's atmosphere from the direction of the Yingxian seat, which brings gorgeous meteor shower to the northern hemisphere.

When watching the meteor rain, you must pay attention to safety. You need to choose a place where the weather is clear, the lights are small, and the field of vision is open and unobstructed. The best way to watch is to watch it directly. You can lie on the cushion and cover the sky as much as possible (you don't have to stare at the radiation point). When there is a moon, the sight should avoid the moonlight. When watching the midway, you need lighting. You can use red light flashlight to avoid the eyes of the eyes from being affected by light.

The Beginning of Autumn

The Beginning of Autumn (Liqiuin Chinese) is the 13th solar term of the traditional Chinese calendar. This year it falls on August 7th, at 20:29 (Beijing Time) when the Sun reaches a longitude of 135º. This is also the first solar term of the autumn, when all the plants on Earth are growing into maturity. The Beginning of Autumn does not mean the end of intense heat since the last period of the canicular days is yet to come afterwards.

Astronomical Forecast

Beginning of autumn ——End of Heat

⊙the Sunh

The Sun travels from Cancer to Leo. Currently, Sun activity remains low, with only a few groups of small sunspots on its surface. They can be observed through a telescope with a safe solar filter.

✦The Moonh

The full moon occurs at 09:36 a.m. on August 12th, which meets the 15th day of the 7th lunar month, the Ghost Festival, or Zhongyuan in Chinese. Lying at 361,000 kilometres from the Earth, the full moon is visible throughout the night. ✦Mercuryer

Mercury Appears Currently as an "Evening Star". It Travels from Leo to Virgo in Program Motion. Its Angular distance to the Sunues Increasing But Remains Difficult to BED

♀venusen

Venus travels in prograde motion from Gemini to Cancer. Its angular distance to the Sun continues to decrease. It appears as a "morning star", which is low in the north-eastern sky before sunrise, and can be spotted with the naked eye.

♂marsar

Mars Travels in Program Motion from Aries to Taurus. It rises at 1 a.m. and can be seen from midnight to dawn.

Jupiter Travels in RetroGrade Motion in Cetus. It rises artes design 9 p.m. and can be observed from midnight to dawn.

✦Saturnat

Saturn will be at opposition on August 15th. It rises from the sound-elements sky in the event and can be observed all night.

Meteor Showere

Perseids will reach maximum at 9-10 a.m. on August 13th. The meteor shower can be observed on August 12th and 13th, when its radiant rises at 9 p.m. until dawn the next day.However, some dimmer meteors may not be visible due to the Severe interference of the moonlight.
