Solar Radio Bursts Monitoring at e-Callisto Taiwan-NCU Station

Radio emission is the most important diagnostic tool to investigate the dynamic properties of energetic electrons produced by solar flares, magnetic reconnections, CME-driven shocks, interplanetary shocks, and flaring active regions.To monitor the solar radio bursts (SRBs), the e-Callisto Taiwan-NCU station was established since January 2022 at the campus of National Central University (NCU), Taiwan and started the regular observations in July 2023 with 12-hour coverage per day after testing the facilities and resolving some technical problems.It operates in the frequency range of 45-870 MHz in the beginning, changes to 45-380 MHz in February 2024, and adjusts to 45-80 MHz in April 2024 for better detecting SRB events and minimizing the radio frequency interference from terrestrial sources.The geographical coordinate of Taiwan-NCU station is 24.97N, 121.19E with an altitude of 150 m and the local time is UTC +08 hours.Since the first light of type III radio burst associated with a M2.9 flare was detected on 2023 July 15, more than 300 SRBs were observed till January 2025.As expected, type III bursts including type VI are most commonly observed at Taiwan-NCU station.In our measurements, about half of type VI bursts are found to be flare-related, while more than half of type III bursts occur without flares.Furthermore, most of type II bursts potentially have CME-driven shock associations and the majority of type V bursts are appeared accompanied with flares.In this presentation, we will briefly introduce the instrument facilities of Taiwan-NCU station, demonstrate few SRB events along with their solar associations, and discuss the spectral characteristics of detected SRBs.
