Explanation: On December 8 a full Moon and a full Mars were close, both bright and opposite the Sun in planet Earth’s sky. In fact Mars was occulted, passing behind the Moon when viewed from some locations across Europe and North America. Seen from the city of Kosice in eastern Slovakia, the lunar occultation of Mars happened just before sunrise. The tantalizing spectacle was recorded in this telescopic timelapse sequence of exposures. It took about an hour for the Red Planet to disappear behind the lunar disk and then reappear as a warm-hued full Moon, the last full Moon of 2022, sank toward the western horizon. The next lunar occultation of bright planet Mars will be in the new year on January 3, when the Moon is in a waxing gibbous phase. Lunar occultations are only ever visible from a fraction of the Earth’s surface, though. The January 3 occultation of Mars will be visible from parts of the South Atlantic, southern Africa, and the Indian Ocean.

说明: 在12月8日，于地球天空中与太阳反向的明亮满月和浑圆火星，靠彼此非常近。事实上，从欧洲和北美洲的某些地点看出去，火星通过月亮的后方，发生了月掩火星的景观。而在斯洛伐克东部的科希策市观看，月掩火星发生在即将日出之前，这幅缩时望远镜图像序列，就记录了这个引人入胜的事件。这颗红色行星从消失在月盘后方到复现于暖色的满月边缘，共历时约1小时，该时这轮2022年的最后满月已向西方的地平线沉降。下次的月掩明亮火星将发生在1月3日的新年期间，届时月亮会带为盈凸月相。不过这例月掩火星，只有在南大西洋、非洲南和印度洋等地区方可见。
