Solar Eclipse

Explanation: On April 20, 2023 the shadow of a New Moon raced across planet Earth’s southern hemisphere. When viewed along a narrow path that mostly avoided landfall, the Moon in silhouette created a hybrid solar eclipse. Hybrid eclipses are rare and can be seen as a total eclipse or an annular “ring of fire” eclipse depending on the observer’s position. Viewers of this much anticipated hybrid event were able to witness a total solar eclipse while anchored in the Indian Ocean near the centerline of the eclipse track off the coast of western Australia. This ship-borne image from renowned eclipse chaser Fred Espenak captured the active Sun’s magnificent outer atmosphere, or solar corona, streaming into space. The composite of 11 exposures ranging from 1/2000 to 1/2 second, taken during the 62 seconds of totality, records an extended range of brightness to follow alluring details of the corona not quite visible to the eye.

日食

说明: 于2023年4月20日，沿着基本上避开陆地的狭窄路径，新月的影子飞掠过地球的南半球，带来了结合日环食与日全食的混合日食。混合日食相当罕见，至于是见到日全食或是有火之环之称的日环食，端视观察者所在的位置而定。譬如这例众所引颈期盼的混合日食，在邻近西澳大利亚海岸的印度洋上，搭乘锭泊于全食路径中心线附近船只的追日食者，就目睹了日全食。这张由著名的追日食者艾斯潘纳克（Fred Espenak）摄于船上的日食影像，捕捉到活跃太阳的壮丽外层大气（日冕）向太空泛流的景象。这幅主题影像，组合自摄于62秒日全食期间、曝光时间介于1/2000秒到1/2秒之间的11张照片，以记录全食阶段肉眼难以见到的日冕细微结构。
