The reporter learned from the Purple Mountain Observatory of the Chinese Academy of Sciences that my country’s comprehensive solar exploration satellite “Kuafu-1” recently obtained hard X-ray images of the sun and released them to the public. This is also the first scientific image released by Kuafu-1 after its launch.

It is reported , which is currently the only hard X-ray image of the sun taken from a near-Earth perspective in the world, and its image quality has reached the international advanced level.
Gan Weiqun, Chief Scientist of “Kuafu-1”, introduced that the image released this time is an M-class solar flare that erupted at 1 o’clock (UT) on November 11 The image was taken by the hard X-ray imager (HXI) onboard the satellite. Although it is still in the testing period, the imaging effect is already very good, from which the details of the eruption and the fine structure of the sun can be identified.

The full name of “Kuafu-1” satellite is Advanced Space-based Solar Observatory (ASO-S), which is a comprehensive solar exploration satellite. On October 9, 2010, it was successfully launched at the Jiuquan Satellite Launch Center. The scientific goal of the satellite is “one magnetic storm and two storms”, that is, to simultaneously observe the solar magnetic field and the two most violent eruptions on the sun—flares and coronal mass ejections, and to study their formation, evolution, interaction, and correlation. Support for space weather forecasting. The hard X-ray imager is one of the three major payloads of the satellite. It was developed by the Purple Mountain Observatory of the Chinese Academy of Sciences and undertakes the task of observing the non-thermal radiation of solar flares during the “one magnetic storm and two storms”.

Zhang Zhe, chief designer of the payload of the hard X-ray imager, and Su Yang, a data scientist, introduced that since “Kuafu-1” entered orbit for more than a month, the hard X-ray imager has carried out various on-orbit tests and calibrations. At present, the load state is normal, and all functions and performances meet the requirements of the design indicators, and it has been successfully put into scientific observation activities. After the subsequent calibration is completed, the payload imaging quality is expected to be further improved.
