Chinese weather satellite Fengyun-3E broadcasts high-precision solar images



China’s Fengyun-3E (FY-3E) weather satellite released its first set of high-precision, multiband solar images on Thursday, according to a report released by China Science Daily on Friday.

The imager captured extreme ultraviolet images of the sun, x-rays and the intensity of fine spectral radiation in the short-wave ultraviolet infrared band. The images were monitored by an extreme ultraviolet x-ray solar imager and a solar spectral irradiance monitor attached to the FY-3E satellite.

Researchers can better monitor and predict solar activity levels thanks to the recently released images, said Zhang Peng, deputy director of the National Meteorological Satellite Center (NSMC).

The FY-3E satellite was launched on July 5. It is the world’s first morning weather satellite for civilian use.

The Extreme Ultraviolet X-ray Solar Imager is the first solar space telescope in China. It can monitor the activity of the solar corona, capture the process of solar storms, predict changes in geospatial electromagnetic fields and charged particles, and send warnings of the impact of solar activities on aviation, navigation, telecommunications , electricity networks and pipelines.

The Solar Spectral Irradiance Monitor can record the subtle changes in the incoming energy from the sun to the earth. The instrument plays a vital role in accurately monitoring energetic changes in the Earth’s climate system.

Continuous monitoring of solar activity is crucial as solar bursts could affect the Earth’s magnetic field and ionosphere, disrupt the operation of artificial satellites, and even cause the power grid to fail.

The recently released images were taken in cooperation with the NSMC, the National Astronomical Observatories of the Chinese Academy of Sciences and Peking University.
