论文摘要
磁能突然释放在太阳上驱动强大的太阳耀斑和冠状质量弹出。关键问题是难以预测强大太阳爆发的发生时间和位置，即导致近地环境的高影响空间天气障碍的爆发。太阳无线电成像有助于识别易受强烈耀斑和能量冠状质量弹出的活动区域的磁场特性。在X波段（8.1-9.3 GHz）上与Arecibo天文台的12米射电望远镜在X波段（8.1-9.3 GHz）上映射，可以监测活性区域的亮度温度与磁复杂性的发展相关的亮度温度的演化，这可能导致强烈的爆发。对于将来更好的预测策略，这种基于地面的无线电观察到高空间和时间分辨率以及完整的极化能力，不仅具有巨大的潜力，不仅可以理解太阳喷发的磁活动，而且还可以揭示粒子加速机制和其他令人兴奋的科学。
The sudden release of magnetic energy on the Sun drives powerful solar flares and coronal mass ejections. The key issue is the difficulty in predicting the occurrence time and location of strong solar eruptions, i.e., those leading to the high impact space weather disturbances at the near-Earth environment. Solar radio imaging helps identify the magnetic field characteristics of active regions susceptible to intense flares and energetic coronal mass ejections. Mapping of the Sun at X-band (8.1 -- 9.3 GHz) with the 12-m radio telescope at the Arecibo Observatory allows monitoring of the evolution of the brightness temperature of active regions in association with the development of magnetic complexity, which can lead to strong eruptions. For a better forecasting strategy in the future, such ground-based radio observations of high-spatial and temporal resolution, along with a full polarization capability, would have tremendous potential not only to understand the magnetic activity of solar eruptions, but also for revealing the particle acceleration mechanism and additional exciting science.
