Mysterious red appears in the sky in western China. What is the cause of this red color?

Because I haven't seen it, I don't know what it looks like, I don't know much about it, and it may even be a passerby, so I need to learn from it and share it with you.

Recently, mysterious "visions" appeared in the sky in parts of Qinghai Province. Different from the previous "horizon" in China and other areas of Blue Star, this time the "horizon" is red in color and its halo is similar to a comet. Some netizens said that this is probably the real UFO arrival on the earth. Of course, some scientific netizens think that this may be another space launch activity or space test of spacecraft, because of the reflection angle of the sun light, it is a red halo.

If the mysterious "vision" photographed in the other direction is white, it is not considered, but the unknown "vision" in memory is really not red. According to eyewitnesses, this mysterious "scene" in the sky has passed through a wide range. Personally, I think it should also be another space launch activity or spacecraft space test conducted by human beings.

If you look up in the wild and see such a mass of red objects moving in the air, the timid may be directly scared.

Therefore, in fact, this statement does not give some specific explanations, and it is very clear what this thing is. Personally, I prefer that this is an experiment or something, so that there is such a mass of red, but I am not sure.

Whatever the reason, there are absolutely no aliens or other extraordinary ideas. I hope to have the opportunity to see such a vision.
