2022年将会有四次超级满月。根据“超级月亮”的定义，满月在近地点附近，即在给定轨道上离地球最近的距离至少为90%，那么今年的“超级月亮”日期分别是5月16日、6月14日、7月13日和8月12日。近地点附近的满月确实是地球天空中最亮、最大的。但满月之间的大小和亮度差异相对较小，仅凭肉眼很难与其他满月进行实际比较。这张6月14日拍摄的超级月亮和天空景观混合了两张照片。这个满月也被北半球的天文观测者称为“草莓月”。连续的短曝光和长曝光使得在完全阳光照射的月球近侧的熟悉特征与微弱的月球日冕和大气云景在同一张图像中被看到。这些照片是在中国重庆上空拍摄的。

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.
