7月13日，这张精心策划的长焦照片记录了斯洛伐克东部卢博夫纳城堡上空升起的满月。摄影师距离城堡城墙约3公里，距离满月近地点约35.7万公里，近地点是其椭圆轨道上最近的点。有些人把近地点附近的满月称为超级月亮，与发生在月球平均距离约38.4万公里附近的满月相比，近地点附近的满月在地球天空中更亮、更大。当然，任何靠近地平线的满月都可以通过密集的清晰大气显示出长视线的折射效应。在这张图片中，大气折射产生了轻微的绿色闪光，在靠近顶部的薄云的框架下，在七月近地点满月的底部边缘有一个粗糙的红色边缘。

On July 13 this well-planned telephoto view recorded a Full Moon rising over Lubovna Castle in eastern Slovakia. The photographer was about 3 kilometers from the castle walls and about 357,000 kilometers from this Full Moon near perigee, the closest point in its elliptical orbit. Known to some as supermoons, full moons near perigee are a little brighter and larger in planet Earth's sky when compared to full moons that occur near the average lunar distance of around 384,000 kilometers. Of course any Full Moon near the horizon can show the effects of refraction over a long sight-line through dense clear atmosphere. In this image, atmospheric refraction creates the slight green flash framed by thin clouds near the top, with a ragged red rim along the bottom edge of July's perigee Full Moon.
