Moonrays of August

Explanation: 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.

说明: 在8月1日太阳西落时，一轮满月冉冉升起。在为期将近1个月的绕地轨道上，这轮满月出现在最靠近地球的近地点附近，因此比寻常的满月更大更亮，并以2023年的第二个超级月亮之姿，照亮了地球各地的夜空。而在西西里．拉古萨市的上空，云层更为超级月亮照耀的夜空，带来戏剧性的辐射状月亮云隙光。 2023年的下一轮满月，也将在8月的夜晚绽放光芒。当太阳在8月30/31西沉时，满月将再升起，成为蓝月、同一个月份的第二轮满月。蓝月每2到3年才会出现一次，这是因为月亮要经过将近一个历月，才能完成一个月相周期（29.5天）。这轮出现在近地点附近的八月蓝月，将是2023年的第三个超级月亮。
