业余无线电报告网络，如反向信标网络（RBN），PSKReporter和弱信号传播网络，是遥感电离层的强大工具。这些自愿建立和运行的网络提供了真实的时间和档案数据，可用于空间天气业务，预报和研究。研究全球和局部效应的潜力是存在的。通过检查GOES 15卫星探测到的X2.9级太阳耀斑对RBN观测到的HF传播路径的影响，证明了这样一个网络探测空间天气扰动的能力。在太阳耀斑之前，RBN观测到多个大陆之间的强HF传播条件，主要是欧洲，北美和南美。在GOES 15探测到太阳耀斑后，全球RBN传播路径的数量下降到之前观测的35%以下。耀斑过后，RBN显示HF传播条件逐渐恢复。
Amateur radio reporting networks, such as the Reverse Beacon Network (RBN), PSKReporter, and the Weak Signal Propagation Network, are powerful tools for remote sensing the ionosphere. These voluntarily constructed and operated networks provide real‐time and archival data that could be used for space weather operations, forecasting, and research. The potential exists for the study of both global and localized effects. The capability of one such network to detect space weather disturbances is demonstrated by examining the impacts on RBN‐observed HF propagation paths of an X2.9 class solar flare detected by the GOES 15 satellite. Prior to the solar flare, the RBN observed strong HF propagation conditions between multiple continents, primarily Europe, North America, and South America. Immediately following the GOES 15 detection of the solar flare, the number of reported global RBN propagation paths dropped to less than 35% that of prior observations. After the flare, the RBN showed the gradual recovery of HF propagation conditions.
