Northern regions of China may have the opportunity to observe auroras in the coming days. According to the National Space Weather Monitoring and Warning Center, following two consecutive solar flares on November 5, additional flares occurred at 19:19 Beijing Time on November 5 and 06:07 on November 6, accompanied by significant coronal mass ejections.
As a result, auroras may be visible in northern China, with areas such as Mohe in Heilongjiang, Xinjiang, and Inner Mongolia potentially experiencing rare red-green aurora displays. Guo Jianguang, head of the Space Weather Forecast Office at the center, explained that auroras are produced when solar particles enter the atmosphere and collide with atmospheric molecules at varying altitudes.
Different colors correspond to different altitudes—red auroras typically appear at heights of 200–400 kilometers, while green auroras occur at lower altitudes. In China, auroras are usually observed as red due to their distant origin. However, during intense geomagnetic storms, such as those in May last year, mixed red-green auroras can be seen in high-latitude regions like Mohe.
