4月20日,新月的阴影沿着一条狭窄的路径快速穿过地球的南半球,形成了罕见的日环食或混合型日食。从西澳大利亚海岸外的印度洋出发,船上的日食追逐者可以在日全食轨迹的中心线附近停泊,目睹62秒的日全食。这张由船载的日食图像捕捉到了活跃的太阳壮丽的外层大气或太阳日冕流进太空。它由11次曝光组合而成,曝光时间从1/2000秒到1/2秒不等,它记录了一个扩展的亮度范围,以跟踪日冕在日全食阶段肉眼不太可见的细节。当然,日食往往是成对出现的。5月5日,下一个满月将在半影月食中与地球阴影的黑暗内部擦肩而过。2023年4月日全食画廊:向APOD提交的重要作品

Along a narrow path that mostly avoided landfall, the shadow of the New Moon raced across planet Earth's southern hemisphere on April 20 to create a rare annular-total or hybrid solar eclipse. From the Indian Ocean off the coast of western Australia, ship-borne eclipse chasers were able to witness 62 seconds of totality though while anchored near the centerline of the total eclipse track. This ship-borne image of the eclipse captures the active Sun's magnificent outer atmosphere or solar corona streaming into space. A composite of 11 exposures ranging from 1/2000 to 1/2 second, it records an extended range of brightness to follow details of the corona not quite visible to the eye during the total eclipse phase. Of course eclipses tend to come in pairs. On May 5, the next Full Moon will just miss the dark inner part of Earth's shadow in a penumbral lunar eclipse.
