Observational results of MUSER during 2014–2019

The solar radio signal that can be received by the ground-bas ed telescopes covers a wide frequency range, allowing us to monitor the complex physica l processes occurred from the solar surface to the vast interplanetary space. MingantU SpEctra l Radioheliograph (MUSER), as the latest generation of solar dedicated radio spectral-imaging inst rument in the centimeter-decimeter wavelengths, has accumulated a large number of observational data since i ts ommissioning observation in 2014. This paper presents the main observational results identified by MUSER from 2014 to 2019, including the quiet Sun and 94 solar radio burst events. We find that there are 81 ev ents accompanied with Geostationary Operational Environmental Satellites (GOES) soft X-ray (SXR) flares, among which the smallest flare class is B1.0. There are 13 events without accompanying any recorded flares, among which the smallest SXR intensity during the radio burst period is equivalent to level-A. The main characteristics of all radio burst events are presented, which shows the powerful abilit y of MUSER to capture the valuable information of the solar non-thermal processes and the importance for sp ace weather. This work also provides a database for further in-depth research.
