China plans to build a telescope for constant monitoring of the Sun

(ORDO NEWS) — Our dawn is very active, so solar flares are very common. At the same time, coronal mass is ejected into space – streams of high-energy particles.

Strong emissions can harm not only astronauts and satellites, but also terrestrial communication and power supply systems. In China, they decided to take a closer look at solar activity using a new telescope.

What is known about the new radio telescope

The Daocheng Solar Radio Telescope (DSRT) is being built on a site high in the Tibetan Plateau in Sichuan province.

The tool consists of 313 antennas, each of which has a diameter of 6 meters. The antennas will be arranged in a circle with a 100m tower in the center.

All 313 array antennas will work in concert according to a specially written algorithm. Construction is expected to be completed by the end of 2022.

The DSRT telescope will work in tandem with another solar-observing telescope, Mingantu, under construction in Inner Mongolia.

DSRT will be the world’s largest circular array for radio imaging of the Sun and will enable more accurate observation of coronal mass ejections.

Mingantu is a scintillation telescope that will create a spatial map of the distribution of the solar wind from the distortion of radio signals from deep space. These will be indirect observations, while the DSRT will follow the coronal mass ejections directly.

China appears to be gearing up for a massive presence in space as space weather determines space communications capabilities and safe trajectories for spacecraft, as well as sharpening the health of astronauts.

This is especially important outside the Earth‘s magnetic field, such as in the orbit of the Moon, where solar wind particles can damage ship equipment and human health.

Recall that in April a series of flares took place on the Sun, the most powerful of which occurred on April 17. Then the eruption occurred at the eastern extremity of the Sun, the coronal mass ejection generated by it was not directed to the Earth. At the same time, it caused a brief radio outage and was classified as a type II solar radio burst.
