In what month does Mohe Aurora appear?

Mohe aurora appears in June and July, but it may not be seen. The locals suggest that it is best to go twice a year. One is around the summer solstice, that is, in June and July. At this time, there is not only the annual summer solstice festival, but also the opportunity to see the aurora in the local "Arctic Village", but the aurora is hard to find, and even the locals rarely see it. The other is deep winter, that is, the months of 12 and 1. Coming to Mohe at this time is not only an experience of "freezing in the cold", but also the possibility of seeing the aurora. The winter tourism projects in Mohe are all related to ice and snow. The vast Xue Hai in the Arctic Village, the ice lanterns in Mohe County, the snow sculpture exhibition and the horse-drawn sledge are all very interesting.

Aurora morphology

According to the study of the distribution of aurora, the shape of aurora is not a circle with the geomagnetic pole as the center, but an ellipse. The spectral range of aurora is about 3 100 ~ 6700 angstroms, and the most important spectral line is the oxygen atom green line of 5577 angstroms, which is called the aurora green line. Most auroras appear at 90- 130 km above the earth. 1959, the height measured by the Northern Lights at one time was 160 km, and the width was over 4800 km. But some auroras are much higher, and the height can reach 560- 1000 km.
