每天晚上观察月亮，你会看到它可见的阳光部分逐渐变化。从新月到满月再到新月，一个月相周期约为29.5天。从左上到右下，这张7x4的望远镜图像矩阵捕捉了连续28个晚上的月相范围，从7月29日晚上到8月26日早上，几乎是满月。没有在新月前后24小时左右拍摄的照片，当时月相最多是一个狭窄的新月，靠近太阳，很难看到。为了找到大部分晴朗的地中海天空，需要偶尔进行一次公路旅行来完成这个月球周期项目，在傍晚拍摄上半月，在傍晚和清晨拍摄下半月。由于所有的图像都以相同的比例注册，您可以使用这个矩阵来跟踪月球在单个月期间的视大小变化。为了额外加分，找到发生在近地点最近的月相。今晚：国际观月夜

Observe the Moon every night and you'll see its visible sunlit portion gradually change. In phases progressing from New Moon to Full Moon to New Moon again, a lunar cycle or lunation is completed in about 29.5 days. Top left to bottom right, this 7x4 matrix of telescopic images captures the range of lunar phases for 28 consecutive nights, from the evening of July 29 to the morning of August 26, following an almost complete lunation. No image was taken 24 hours or so just after and just before New Moon, when the lunar phase is at best a narrow crescent, close to the Sun and really hard to see. Finding mostly clear Mediterranean skies required an occasional road trip to complete this lunar cycle project, imaging in early evening for the first half and late evening and early morning for the second half of the lunation. Since all the images are registered at the same scale you can use this matrix to track the change in the Moon's apparent size during the single lunation. For extra credit, find the lunar phase that occurred closest to perigee. Tonight: International Observe the Moon Night
