摘要
太阳上过渡区成像仪（SUTRI）搭载于空间先进技术演示卫星（SATech-01），该卫星于2022年7月发射至500 km高的太阳同步轨道，旨在测试我们新研制的Sc-Si多层反射镜与2k×2k EUV CMOS成像相机的在轨性能，并借助3 nm滤光带宽在Ne VII 46.5 nm谱线处获取全日面太阳图像。SUTRI采用孔径18 cm的Ritchey-Chretien光学系统。在轨观测显示，无图像稳定系统下SUTRI图像视场为41.6'×41.6'、空间分辨率中等为8"。SUTRI图像常规 cadence 为30 s，因地球阴影时间约占SATech-01轨道周期的1/3，每日太阳观测时长约16小时。每日获取约15 GB数据，经处理后在线发布。SUTRI图像颇具价值，因为Ne VII 46.5 nm谱线形成于太阳大气0.5 MK温度区间，现有太阳成像仪极少对该区间采样。SUTRI观测将建立太阳低层大气与日冕结构间的联系，并增进我们对耀斑、暗条爆发、日冕喷流与日冕物质抛射等多类太阳活动的理解。
