Kodaikanal solar observatory radio spectrograph

Abstract

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.
