The Indian Institute of Astrophysics (IIA) has commissioned a low frequency (<100 MHz) spectrograph at its Kodaikanal Solar Observatory (KSO) for coordinated observations of transients in the solar atmosphere with other existing optical observing facilities there. The hardware set-up and initial observations are presented. The availability of different instruments in the same observatory helps to quickly plan and jointly observe the energetic phenomena and their signatures in all the three major atmospheric regions of the Sun, i.e. photosphere, chromosphere and corona.

Kodaikanal 太阳天文台射电光谱仪

印度天体物理研究所 (IIA) 已在其 Kodaikanal 太阳天文台 (KSO) 启用了一台低频 (<100 MHz) 光谱仪，用于与那里现有的其他光学观测设施对太阳大气中的瞬变进行协调观测。介绍了硬件设置和初始观察。同一天文台中不同仪器的可用性有助于快速规划和共同观察太阳所有三个主要大气区域（即光球层、色球层和日冕）的能量现象及其特征。
