The sun's "sneeze" arrived as predicted! China's NationalCenter for Space Weather (NCSW) forecast geomagnetic activities (地磁活动) to happen from March 24 to 26. According to the data, the earth experienced the storm that lasted Yor 12hours on March 25. Geomagnetic storms can shoot out a hugeamount of material and carry a strong magnetic field, whichcauses major changes in the earth's magnetic environment.
"Geomagnetic storms can influence (影响) radio waves and cause problems for ground communication and satellite signals (卫星信号)," Professor Cai Zheng from Tsinghua University told Xinhua. This can influence the accuracy of navigation systems (导航系统) and the quality of signals for phones and satellite TV, Strong geomagnetic storms can also influence powersystems, even resulting in power outages.
Geomagnetic storms can also influence the migration and navigation abilities of animals. Forexample, they can influence homing pigeons' ability to find their way, making it difficult forthem to return home.
★Shortly after the recent storm, the topic of "geomagnetic storms and sleep" appeared on Sina Weibo with some Internet users complaining that they had trouble sleeping. However, it was just a convenient excuse. "Geomagnetic storms usually don't influence human health," Zong Weiguo at China Meteorological Administration said.
Not only do the storms have minimal influence on humans, they also send an unexpected gift—auroras (极光). On the early morning of March 25, auroras appeared in Genhe in Inner Mongolia and Mohe in Heilongjiang.
