CALLISTO Spectrometer at IISER-Pune

A CALLISTO spectrometer to monitor solar radio transient emissions from $approx 0.8-1.6~R_{odot}$ (above photosphere) is installed at IISER, Pune, India (longitude $73^{circ} 55$ E and latitude $18^{circ}31$ 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.
