沒想到啊，APOD也是超級月亮

There are four Full Supermoons in 2022. Using the definition of a supermoon as a Full Moon near perigee, that is within at least 90% of its closest approach to Earth in a given orbit, the year’s Full Supermoon dates are May 16, June 14, July 13, and August 12. Full Moons near perigee really are the brightest and largest in planet Earth’s sky. But size and brightness differences between Full Moons are relatively small and an actual comparison with other Full Moons is difficult to make by eye alone. Two exposures are blended in this supermoon and sky view from June 14. That Full Moon was also known to northern hemisphere skygazers as the Strawberry moon. The consecutive short and long exposures allow familiar features on the fully sunlit lunar nearside to be seen in the same image as a faint lunar corona and an atmospheric cloudscape. They were captured in skies over Chongqing, China.

2022年有4個(gè)超級滿月。超級滿月定義為出現(xiàn)在近地點(diǎn)附近的滿月，而在繞地球的軌道上，是指與地球的距離超出最小距離不到10%的滿月；今年的超級滿月分別出現(xiàn)在5月16日、6月14日，7月13日和8月12日。近地點(diǎn)附近的滿月，的確是地球天空中最亮和最大的月輪。不過，滿月之間的大小與亮度差異不大，僅憑肉眼難以分辨和比較。這幅呈現(xiàn)超級月亮與天空的主題影像，融合了2張攝于6月14日的照片。而對北半球的觀星者來說，這輪滿月亦稱為莓月。用短曝光和長曝光照片組合出的這幅影像，讓我們得以同時(shí)見到月球正面受陽光照耀的熟悉月面特征，以及昏暗的月冕和周圍的云層結(jié)構(gòu)。這些照片記錄了出現(xiàn)在中國重慶天空的景觀。
