Abstract
Our study focused on two types of solar radio bursts observed on November 29th, 2020, at 12:54 UT and 12:56 UT, respectively. In addition to seeing the radio burst appear in the spectral dynamic spectrum, measurements of the burst's energy, frequency drift rates, and plasma frequency have been made. Prior to the type II burst, a flare of class M4.44 was detected by the GOES satellite and seen in x-ray flux data. AR 2790 generated the solar flare, but it was hidden behind the southeastern limb of the Sun, so the active region was not visible in the solar disk on November 29th, 2020. As far as solar flare explosions go, this was the biggest in three years since October 20th, 2017, from AR2685. Due to the proximity of these events, it is thought that the solar flare triggered a partial-halo CME at 13:25UT. From the CME’s velocity and flare association, we infer that it is an impulsive CME.
