“夸父一号”卫星观测数据向海内外试开放

我国首颗综合性太阳探测卫星“夸父一号”准实时观测数据12日起向国内外试开放。经过近半年的在轨调试，“夸父一号”卫星已经获得大约80TB的原始太阳观测数据。

The satellite observation data of the Advanced Space-based Solar Observatory (ASO-S) was open for trial use at home and abroad, authorities said on Wednesday.

中国科学院紫金山天文台4月12日表示 ，中国首颗综合性太阳探测专用卫星——“夸父一号”观测数据现已向海内外试开放。

A data release and training conference on how to use the observation data was held online, which was attended by nearly 400 solar physics experts from 25 countries.

4月11日至12日，“夸父一号”观测数据试开放全球发布暨数据使用培训会在线召开，来自25个国家和地区的近400位太阳物理专家学者参会。

ASO-S, China's first comprehensive solar exploration satellite, was launched in October last year from the Jiuquan Satellite Launch Center in northwest China.

“夸父一号”于2022年10月在酒泉卫星发射中心成功发射。

After half a year of in-orbit commissioning, the satellite has obtained about 80 TB of raw solar observation data.

经过近半年的在轨调试，“夸父一号”卫星已经获得大约80TB的原始太阳观测数据。

Speaking at the conference, Gan Weiqun, the satellite's chief scientist, provided a comprehensive overview of the scope of the trial opening data, including all observations from the Hard X-ray Imager (HXI) since April 1, some observations from the Full-disk Vector MagnetoGraph (FMG), and some observations from the Lyman-alpha Solar Telescope (LST).

“夸父一号”首席科学家、中国科学院紫金山天文台研究员甘为群在会上公布了此次“夸父一号”卫星观测数据试开放的范围，包括自4月1日起的太阳硬X射线成像仪(HXI)的全部观测数据、全日面矢量磁像仪(FMG)的部分观测数据、莱曼阿尔法太阳望远镜(LST)的部分观测数据。

"In the future, we will make adjustments based on the satellite's in-orbit testing, eventually making all of the satellite's observations available to the public in quasi-real time," Gan said.

甘为群说：“后续，科学团队将根据卫星在轨测试情况适时调整，最终达到卫星全部观测数据的准实时开放。”

The two-day conference, which began on Tuesday, was co-hosted by the Purple Mountain Observatory under the Chinese Academy of Sciences (CAS), the National Space science Center under the CAS, and the National Space Science Data Center.

为期两天的会议由中国科学院紫金山天文台、中国科学院国家空间科学中心和国家空间科学数据中心联合主办。
