CALLISTO Spectrometer at IISER-Pune [IMA]

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 calledpycallisto’.
