What is the weather forecast for the universe?

Soon, people will hear such a cosmic weather forecast-"Now report the cosmic weather forecast from X to X in 2020. Because of the gradual strengthening of solar activity, an activity center has been formed in a certain area on the surface of the sun. Large flares with a probability of 7% above magnitude 7 are expected to emit powerful X-rays and high-energy particle streams. In the meantime, please suspend all extravehicular activities of the spacecraft and outdoor activities on the surface of the moon ... "

In 2 1 century, people's activities in space have increased, and manned spacecraft will be attacked by high-energy particle rain, plasma solar wind and magnetic explosion when flying in space. According to calculation, the protective effect of spacecraft wall is only 1‰ of the atmosphere, while the protective effect of spacesuit is less than 1‰ of the atmosphere. Cosmic rays can not only destroy human cells, but also easily cause skin cancer, causing great damage to spacecraft instruments. Scientists collect all kinds of data through observation networks on the earth and satellites, analyze the solar weather activities and the changes of the solar surface magnetic field with computers, and predict the changes of solar activities and the cosmic environment. In the cosmic activities of 2 1 century, the cosmic weather forecast is absolutely indispensable.
