When were the sunrises and sunsets from winter solstice and summer solstice last year?

Summer solstice 4:30- 19: 10 winter solstice 6:50- 17:00 This is only an approximate time, and the change of air pressure should be considered. Sunshine time, or sunrise and sunset time, is different in different places.

Summer solstice is one of the 24 solar terms, which occurs on June 20th, or 2 1, or 22nd of the Gregorian calendar every year. On the day of summer solstice, the sun moves to 90 degrees of the yellow meridian (summer solstice, currently in Gemini), and the position where the sun directly hits the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year.

Astronomical experts say that the solstice in summer is the turning point of the sun. After this day, I went back. The direct sunlight point moved southward from the Tropic of Cancer, and the daylight in the northern hemisphere became shorter and shorter day by day. After the summer solstice, the Tropic of Cancer and its northern region, the midday sun altitude angle also began to decrease. At the same time, after the arrival of the summer solstice, the stars in the night sky gradually became summer stars.

At sunset, sunlight is Rayleigh scattered by the influence of the earth's atmosphere, so the sky is usually full of Xia Hong. The color of sunset can be enhanced by the atmospheric phenomena of the earth, such as clouds, smoke, fog and man-made waste gas in nature. In addition, volcanic ash released by volcanic eruption will also have an impact.

Sunset is often brighter than sunrise because the atmosphere is exposed to sunlight all day. In addition, there is more dust in the lower atmosphere at sunset than at sunrise. This is because the sun shines on the earth's surface all day, which reduces the relative humidity, but increases the wind speed and turbulence, leaving dust in the air.
