星空有约丨太阳“打喷嚏”，地球会“感冒”吗？

Core Points - Recent solar activity has seen multiple significant solar flares, including X1.8, X1.1, M7.4, M8.6, and X1.7 flares, indicating heightened solar activity [1][2] - Solar flares and coronal mass ejections (CMEs) can impact space weather, which affects high-tech fields such as aerospace, aviation, and communications, although ground-level human health is not at risk [2][5] - The current solar activity is reportedly weaker compared to last year, with solar flares categorized by intensity levels (C, M, X) and geomagnetic storms classified as weak, medium, or strong [2][5] Industry Developments - The "Xihe" satellite, China's first solar exploration satellite, is part of a broader initiative to enhance space weather monitoring capabilities [2][5] - The completion of the Meridian Project Phase II marks a significant advancement in China's ground-based monitoring of space weather across all layers of the sun-Earth system [5] - Plans for the "Xihe II" solar exploration project aim to position a satellite at the L5 Lagrange point, enabling advanced observation and tracking of solar activities directed towards Earth, enhancing predictive capabilities for space weather [5]
