8月1日,太阳落山,满月升起。在近地点附近,也就是月球轨道上最近的点,比平均水平更亮的月球盘照亮了地球周围的夜空,成为2023年的第二个超级月亮。在西西里岛的拉古萨上空,云层在月光下的天空投下了不同的阴影,形成了壮观的月色黄昏。2023年的下一次满月也将在8月的夜晚出现。当太阳在8月30日或31日落下时升起,这是一个月内的第二次满月,被称为蓝月亮。蓝月亮每2年或3年才出现一次,因为月相几乎需要一个日历月(29.5天)才能完成一个完整的周期。但8月的蓝月亮也将在近地点附近,这是2023年的第三次超级月亮。

A Full Moon rose as the Sun set on August 1. Near perigee, the closest point in its almost moonthly orbit, the brighter than average lunar disk illuminated night skies around planet Earth as the second supermoon of 2023. Seen here above Ragusa, Sicily, cloud banks cast diverging shadows through the supermoonlit skies, creating dramatic lunar crepuscular rays. The next Full Moon in 2023 will also shine on an August night. Rising as the Sun sets on August 30/31, this second Full Moon in a month is known as a Blue Moon. Blue moons occur only once every 2 or 3 years because lunar phases take almost a calendar month (29.5 days) to go through a complete cycle. But August's Blue Moon will also be near perigee, the third supermoon in 2023.
