Moon Position

Have you ever wished you could get lucky enough to capture one of those photographs with the moon perfectly positioned over your favorite mountain scene?  Rather than just hoping for good luck, you can use this moon position calculator to plan your photograph.  Enter the date you're interested in, and the position of the moon is shown for times around sunrise and sunset.

Times near sunrise and sunset were chosen to optimize the brightness of the moon relative to the surrounding landscape.  More than 1/2 hour before sunrise and 1/2 hour after sunset, the landscape will be very dark.  More than 1/2 hour after sunrise and 1/2 hour before sunset, the moon will be washed out in the bright sky.
