2023 年 4 月 20 日,一輪新月的陰影劃過地球的南半球。當沿著一條狹窄的路徑觀看時,月球的剪影形成了一次混合日食。混合日食非常罕見,根據觀測者的位置,可以看到全食或 "火環 "環食。這次令人期待的混合日食事件的觀測者是在澳大利亞西部海岸附近的日食軌跡中心線附近的印度洋上停泊時目睹日全食的。這幅由著名日食追逐者弗雷德-埃斯佩納克(Fred Espenak)拍攝的船載影像捕捉到了活躍的太陽的壯麗外層大氣,即日冕,流向太空。在日全食的 62 秒內,共進行了 11 次曝光,曝光時間從 1 / 2000 秒到 1 / 2 秒不等,記錄了更大的亮度範圍,呈現出肉眼無法看到的日冕誘人細節。 弗雷德-埃斯彭納克( 1953 - 2025 )
原文: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)
