Cloudy skies plagued some sky watchers on Sunday as May's Full Flower Moon slipped through Earth's shadow in a total lunar eclipse. In skies above Chile's Atacama desert this telephoto snapshot still captured an awesome spectacle though. Seen through thin high cirrus clouds just before totality began, a last sliver of sunlit crescent glistens like a hazy jewel atop the mostly shadowed lunar disk. This full moon was near perigee, the closest point in its elliptical orbit. It passed near the center of Earth's dark umbral shadow during the 90 minute long total eclipse phase. Faintly suffused with sunlight scattered by the atmosphere, the umbral shadow itself gave the eclipsed moon a reddened appearance and the very dramatic popular moniker of a Blood Moon. 

周日，阴云密布的天空困扰着一些天空观测者，五月的满月在月全食中穿过地球的阴影。在智利阿塔卡马沙漠上空，这张长焦照片仍然捕捉到了令人惊叹的景象。在全食开始之前，透过薄而高的卷云，最后一缕阳光照射下的新月像一颗朦胧的宝石一样闪耀在阴影笼罩的月盘上。这轮满月接近近地点，即椭圆轨道上最近的点。在长达90分钟的日全食阶段，它经过地球暗本影中心附近。在被大气散射的微弱阳光照射下，本影本身给被日食的月亮起了一个红色的外观，并给它起了一个非常引人注目的通俗绰号"血月"。
