2023年4月20日，新月的阴影掠过地球的南半球。当沿着一条狭窄的路径观看时，月球的剪影产生了混合日食。混合月食是罕见的，根据观测者的位置，可以被看作是日全食或环状的“火环”月食。这一备受期待的混合事件的观众能够在西澳大利亚海岸附近日食轨迹中心线附近的印度洋上看到日全食。这张由著名的日食追逐者弗雷德·埃斯佩纳克拍摄的船载图像捕捉到了活跃的太阳壮丽的外层大气，或日冕，流入太空。这张照片是在62秒的日全食期间拍摄的，从1/2000到1/2秒的11次曝光的合成照片，记录了一个扩展的亮度范围，以跟踪眼睛不太可见的日冕的诱人细节。弗雷德·埃斯皮纳克（1953-2025）

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. Fred Espenak (1953-2025)
