我国综合性太阳探测专用卫星“夸父一号”近日获得太阳硬X射线图像，并对外发布。这也是“夸父一号”升空后首次发布科学图像。
 

 

China's solar exploration satellite has transmitted its first solar image since being sent to space in October, according to the Purple Mountain Observatory¹ (PMO) based in east China's Jiangsu Province.

位于江苏省的中国科学院紫金山天文台发布消息称，我国的太阳探测专用卫星“夸父一号”已传回首张太阳硬X射线图像。“夸父一号”卫星于今年10月成功发射。

 

The Advanced Space-based Solar Observatory (ASO-S) -- nicknamed Kuafu-1 in Chinese -- sent hard X-ray imaging of solar flares² that broke out at 1:00 a.m. (Universal Time) on Nov. 11, 2022, said Gan Weiqun, the satellite's principal scientist from PMO under the Chinese Academy of Sciences (CAS).

中国科学院紫金山天文台研究员、先进天基太阳天文台首席科学家甘为群表示，此次发布的太阳硬X射线图像是对2022年11月11日01时（世界时）爆发的一个M级耀斑的成像。“夸父一号”卫星全称先进天基太阳天文台（ASO-S）。

 

Gan said the image was taken by the satellite-loaded hard X-ray imager (HXI). Although still in the testing period, the imaging effect is excellent, allowing the effective identification of both the eruptive details and the fine structure of the Sun.

甘为群表示，图像由卫星载荷硬X射线成像仪（HXI）拍摄。虽然还在测试期，但成像效果已经非常优异，从中可以识别出爆发细节和太阳的精细结构。

 

Kuafu-1 was launched aboard a Long March-2D rocket on Oct. 9 from the Jiuquan Satellite Launch Center in northwest China.

2022年10月9日，我国在酒泉卫星发射中心使用长征二号丁运载火箭，成功将先进天基太阳天文台卫星发射升空。

 

"ASO-S is capable of probing the Sun 24 hours a day for most of the year," said Gan. "Its longest daily time-out is no more than 18 minutes when briefly³ running through the shadow of Earth each day from May to August."

甘为群介绍，“夸父一号”在全年的绝大部分时间可以24小时不间断对日观测。仅仅在每年5至8月，每天会有短暂时间进入地球的阴影，“休息”最长的一天也不超过18分钟。
