The aurora in Mohe appears for several months. The background light of Mohe River may appear all year round, but it is the easiest to see in the summer to 9 days before and after. Because the clear sky in Wan Li often appears in Mohe around the summer solstice, there is no cloud barrier between the North Pole and Mohe, so everyone can see the Northern Lights. Generally speaking, the aurora will be observed every summer to the night around the day, and it will also appear during the day. However, it is not easy to see the aurora because the sunshine is twice as large during the day and the brightness of the aurora is small.
