CALLISTO Spectrometer at IISER-Pune

Abstract

A CALLISTO spectrometer to monitor solar radio transient emissions from $\approx 0.8-1.6R_{\odot }$ (above photosphere) is installed at IISER, Pune, India (longitude $73^{\circ }55^{\prime }$ E and latitude $18^{\circ }31^{\prime }$ N). In this paper, we illustrate the instrumental details (log-periodic dipole antenna and the receiver system) along with the recorded solar radio bursts and radio frequency interferences produced by the thunderstorms in the frequency range 45-870 MHz. We also developed the image processing pipelines using `sunpy' and in-house developed python library called `pycallisto'.
