Event Forecast for Solar Eclipse

Changes in the environmental conditions of the sun and the earth are becoming more and more important to the modern cutting-edge technologies on which modern life and production depend. As mentioned earlier, X-ray flares directly cause disturbance in the earth's ionosphere, thereby affecting earth's shortwave communications. Solar proton events can endanger sensors and control equipment on astronauts and spacecraft, and also pose a radiation threat to passengers and crew flying in high latitudes. In addition, some statistics show that intense solar activity is related to earthquakes, volcanic eruptions, droughts and floods, heart and nervous system diseases, and traffic accidents. Therefore, solar activity and solar-terrestrial physics forecasts are very important. Solar activity forecasts are divided into long-term, medium-term, short-term forecasts and warnings. The solar-terrestrial space environment as a systematic scientific research object began in 1957 when humans entered space. The period from the 1950s to the 1970s was the exploration stage, and people gradually realized the importance of the space environment. Based on a large number of detections, a static model describing the environment was established, and safety predictions were made for some major aerospace activities. After the 1980s, driven by demand, research on the solar-terrestrial space environment has developed rapidly. The International Sun-Terrestrial Forecasting Conference, held every four years since 1979, has been held as scheduled, and its scale has been gradually expanded. In order to unite and coordinate the work of major countries, a joint forecast center was established. Headquartered in the United States, there are 10 regional alert centers located around the world. Our Beijing Regional Warning Center is one of them. After entering the 1990s, scientists vividly called it “space weather”.
