太阳活动磁监测器（SAMM）网络（SAMNet）是未来由英国主导的地面太阳望远镜站国际网络。SAMNet在其全部能力下将持续监测太阳大气层多个高度（从光球层到上色球层）的太阳强度、磁场和多普勒速度场。每个SAMM哨兵将配备一组相同的望远镜，每个望远镜都有不同的磁光滤波器（MOF），以在K~I，Na~D和Ca~I光谱波段进行观测。SAMM台站的一个子集将有白光日冕仪和发射线日冕分光偏振仪。SAMNet的目标是为空间天气研究和预报提供观测数据。目标是实现操作上足够的提前时间，例如2-8小时的耀斑警报，并提供广受欢迎的连续天气图（例如，LoS磁场和速度场，强度），空间分辨率仅受视宁度或衍射极限的限制，节奏为10分钟。各个SAMM哨兵将被连接到其主HQ中心，在那里从所有从站接收的数据将被自动处理，并提前26小时发出耀斑警报。
The Solar Activity Magnetic Monitor (SAMM) Network (SAMNet) is a future UK-led international network of ground-based solar telescope stations. SAMNet, at its full capacity, will continuously monitor the Sun’s intensity, magnetic and Doppler velocity fields at multiple heights in the solar atmosphere (from photosphere to upper chromosphere). Each SAMM sentinel will be equipped with a cluster of identical telescopes each with different magneto-optical filter (MOFs) to take observations in K~I, Na~D and Ca~I spectral bands. A subset of SAMM stations will have white-light coronagraphs and emission line coronal spectropolarimeters. The objectives of SAMNet are to provide observational data for the space weather research and forecast. The goal is to achieve an operationally sufficient lead time of e.g. flare warning of 2-8 hours, and provide much sought-after continuous synoptic maps (e.g., LoS magnetic and velocity fields, intensity) of the lower solar atmosphere with a spatial resolution limited only by seeing or diffraction limit, and with a cadence of 10 minutes. The individual SAMM sentinels will be connected into their master HQ hub where data received from all the slave stations will be automatically processed and flare warning issued up to 26 hrs in advance.
