7. I've never seen anything like this

As an avid gardener, the positions of the sun and moon are very important. I had this in my head, but have never seen it plotted out like this.

Wow!

I'm saving these pictures so I can show them to my pint-sized gardening students.

even with super-duper automated telescopes and digital photography available, some people are still fascinated by the simplest astronomical tool available: the Sun's shadow.
