Description
Solar magnetic field observations are mainly divided into two categories: high-resolution local magnetic field measurements and full-disk magnetic field observations. Over the past four decades, Huairou Solar Observing Station (HSOS) has conducted systematic research on the theory and technology of solar magnetic field observations based on these two categories. For high-resolution local magnetic field observations, the 35-cm Solar Magnetic Field Telescope (SFMT) has accumulated one of the longest homogeneous datasets of solar vector magnetic fields in the world, enabling key discoveries such as flare precursor motions and magnetic supergranule properties. As the world’s first mid-infrared solar magnetic field telescope, AIMS has revolutionized solar magnetic measurements by directly detecting Zeeman splitting at Mg I 12.3 μm and achieving a precision better than 10 Gauss. For full-disk magnetic field observations, the full-disk vector magnetograph SFMM has provided high-cadence full-disk solar vector magnetic field data with unprecedented spatial and temporal coverage, significantly improving the accuracy and reliability of solar activity forecasting and space weather research. The Solar Polar-orbit Observatory (SPO) has delivered unprecedented high-resolution observations of the solar polar regions, enabling breakthrough studies of polar magnetic fields, solar wind origin, and greatly advancing the global understanding of the solar dynamo and space weather drivers. This report presents the detailed characteristics and scientific contributions of SFMT, AIMS, SFMM, and SPO.
