Almost as far as it can be.

An early morning shot as I will be out catching up with a bunch of teachers later that I worked with nearly 30 years ago. I will be out long into the night! Apologies in advance for the lack of comments from me today. The group around AR1785 is developing nicely, the Earth would be swallowed up by it with plenty of room to spare. I am amazed by how the ancient Greeks worked out the distance to the Sun, albeit roughly, with nothing more than naked-eye observations!
