DSRT location in the Sichuan province

Daocheng Solar Radio Telescope (DSRT) is a radio telescope in China, that started its operations in 2023 and is used for solar astronomy. It consists of 313 parabolic antennas of 6-meter diameter each, that form an interferometric array. Antennas are equally spaced and form a circle with a circumference of 3.14 km. [1] At the center of the circle is 100-meters-high calibration antenna. The telescope operation frequencies are between 150 MHz and 450 MHz for detection of coronal mass ejection events. The telescope is located in the mountains on Qinghai-Tibetan Plateau in the Sichuan province, and is operated by the Chinese Meridian Space Weather Monitoring Project II. [2] As of 2023, it is the largest solar telescope in operation. Its construction began in 2021 and was finished in 2022. [3] The operations began in June 2023. [4]
