这两块面板由安全的太阳望远镜和氢α滤镜拍摄的视频帧组成，展示了6月6日（上）和6月18日太阳圆盘和太阳边缘巨大日珥的清晰细节。从中国北京拍摄的照片还显示了国际空间站和中国新天宫空间站在明亮的太阳下的剪影。国际空间站位于底部面板的中心附近，穿过明亮活动区AR2833左侧的太阳圆盘，在一个大的环状太阳灯丝下方。中国的空间站位于太阳活动区AR2827的下方，在顶板的中间偏右，看起来是一个较小的“+”和“-”的组合形状。过境轨道前哨站的照片是用相同的设备和相同的像素比例拍摄的，距离国际空间站约492公里。中国空间站距离摄像机有400多公里。

These two panels, composed of video frames made with a safe solar telescope and hydrogen alpha filter, show remarkably sharp details on the solar disk and giant prominences along the Sun's edge on June 6 (top) and June 18. Taken from Beijing, China, they also show a transit of the International Space Station and China's new Tiangong Space Station in silhouette against the bright Sun. The International Space Station is near center in the bottom panel, crossing the solar disk left of bright active region AR2833 and below a large looping solar filament. China's space station is below solar active region AR2827 and right of center in the top panel, seen as a smaller, combined "+" and "-" shape. The pictures of the transiting orbital outposts were taken with the same equipment and at the same pixel scale, with the International Space Station some 492 kilometers away. China's space station was over 400 kilometers from the camera.
