When is the sunrise today?

The sunrise time today is 5: 43-6: 43.

The time of sunrise will change with the season and the latitude of different places. Traditionally, in the northern hemisphere, the sunrise time from winter solstice is the latest, but in fact, the latest sunrise time should be 65438+1early October. By the same token, the earliest sunrise on the solstice is not in summer, but in early June.

Even in the equatorial region, the time of sunrise and sunset will change a little during the year, and these changes can be expressed by daily trajectory. The time of sunrise and sunset can be calculated by tracking the sun's trajectory, but the calculated time will be slightly different from the real feeling, the calculated sunshine time will be longer than the real feeling, and the calculated night time will be shorter than the real feeling.

The difference between sunrise and sunset:

1, the halo is different. Sunrise: The sun slowly brightens the sky, but their light sources collide, which leads to other natural phenomena such as the sun becoming more and more blurred or gradually changing when touching the sky, resulting in a strong contrast between the sun's rays and the sky, so that the sun can hardly see the complete shape and outline, so the photos taken cannot be accurately focused, and the sun is blurred.

At sunset, when we can still see the sun, the sky is slowly turning black, and the light source of the sun itself continues, so the contrast between the sun and the sky is getting stronger and stronger, so the outline of the sun we see is very obvious against the sky.

2. Scattering is different. At sunrise, sunlight is Rayleigh scattered by dust in the earth's atmosphere, so it is because there is less dust in the atmosphere at sunrise than at sunset. At sunset, due to the influence of the earth's atmosphere, sunlight is Rayleigh scattered.
