Strange astronomical phenomena-bloody sky surprised Zhoushan. What happened?

At 8 pm on May 7, 2022, netizens in Zhoushan City, Zhejiang Province saw a strange blood-red sky vision! Many netizens photographed this mysterious and strange scene from different positions and angles. As can be seen from the video taken by this netizen below, the nearby trees are all normal colors-green, which shows that the color of the camera is normal, but the distant sky in the same picture is bright red. What's going on here?

Previous guess-abnormal refraction and scattering of sunlight My initial guess is that a large number of water droplets in the atmosphere refract and scatter sunlight that has fallen below the horizon. I checked. On May 7th, the sunset time in Zhoushan was 18:32, and the bloody sky appeared around 20:00, with an interval of about 1.5 hours. The sun moves about 22.5 degrees on the celestial sphere (1.5/24*360=22.5), which is actually due to indirect light. I'm not sure ... but soon, this guess was overturned.

Meteorological bureau staff: atmospheric refraction, unknown light source. After the vision happened, some media interviewed the staff of the local meteorological bureau. In the telephone interview, the staff of Zhoushan Meteorological Bureau did not give an exact explanation, only mentioned that there was fog and low-level clouds that day, and said that this (red sky) might be caused by atmospheric refraction, but it was not clear where the red light source came from.

I won't ... there are low-altitude clouds ... and the refracted sunlight can't come in. ...

In this way, the light source can't be the sun, but only from the ground.

Light source locking-fishing boats, however, soon had a reasonable explanation for the source of the red light source: it might come from an ocean-going fishing boat docked in the port. And soon locked in the "accident" fishing boat-an ocean-going ship fishing for saury in the North Pacific Ocean.

According to the investigation of Zhoushan Radio and Television, the incident area happened to be near the dock of Zhouyu Company. Yes, the red sky only occurs in a small area. In fact, we can see from different videos taken by netizens that the sky in some directions is not illuminated by red light, and there is an obvious transition between light and dark.

At that time, an ocean-going ship docked at the dock to catch saury in the North Pacific Ocean, and the light used to catch saury on the ocean-going ship was red! After the red light is reflected by the water surface, it is scattered, refracted and reflected by water droplets and low-altitude clouds in the air, and a strange blood-red sky appears in the video.

In fact, it is not complicated to analyze the causes of this astronomical phenomenon. The main problem is that the information obtained is insufficient, resulting in misjudgment. In fact, according to the red core area of the sky, the position of the light source can be roughly locked, and then the drone can be directly released near the core area to solve the case. ...
