Astronomical Signs August 2

I’m planning a couple trips this fall that will involve night photography, in trying to work out the various astronomical timings, I developed the above graph. The blue zone in the middle is when the sun is up, the blue and black triangles are the moon’s rises and sets. The up triangle means the moonrise time, the down triangle means the moonset. From this relationship, you can get the phase of the moon. If the sun and the moon rise together, you have a new moon. If the moon rises when the sun sets, you have a full moon.
