   Explanation: [5]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
   [6]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, [7]a daytime moon is often
   seen even in urban skies. Captured here in a [8]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.
