Seattle Sky Maps

Choose a month and time to view a sky map for Seattle, WA. If you live anywhere near Seattle, your sky will look very much like the image shown. The 15th of every month was chosen as the day. There are two different times given, because the stars are constantly changing due to the rotation of the Earth. Good luck!
