我们大多数人在晚上看月亮。但月球在我们的地平线上度过的白天时间几乎一样长，尽管在明亮的白天天空中，月球盘看起来很苍白，可能有点难以看到。当然，在白天的天空中，月亮似乎也在经历它的阶段，当它围绕我们美丽的星球运行时，反射的阳光发出了光芒。对于白天的月亮观察者来说，当月球表面可见的阳光部分很大，并且在第一季度之后出现盈亏，或者在第三季度接近月亏时，月亮可能更容易被发现。尽管看起来很不寻常，但即使在城市的天空中，白天的月亮也经常出现。这张摄于3月12日的长焦照片显示，在俯瞰纽约曼哈顿区的热门观景台边缘，一颗日月圆的月亮正排成一线。

Most of us watch the Moon at night. But the Moon spends nearly as many daylight hours above our horizon, though in bright daytime skies the lunar disk looks pale and can be a little harder to see. Of course in daytime skies the Moon also appears to cycle through its phases, shining by reflected sunlight as it orbits our fair planet. For daytime moonwatchers, the Moon is probably easier to spot when the visible sunlit portion of the lunar disk is large and waxing following first quarter or waning approaching its third quarter phase. And though it might look unusual, a daytime moon is often seen even in urban skies. Captured here in a telephoto snapshot taken on March 12, a waxing daytime Moon is aligned near the edge of a popular observation deck that overlooks New York City's borough of Manahattan.
