The Moon, as many of you will know, orbits the Earth in an anticlockwise direction, taking just over 28 days for each orbit. Travelling at just over a kilometre per second, every hour it moves across the background stars by roughly its own diameter (half a degree of arc) Jupiter is currently 415 million miles from Earth, so its apparent motion across the stars is a lot slower.
What this means, of course, is that the Moon's separation from Jupiter gradually reduced overnight, and I crawled out of bed at 5.00am this morning to catch more images of the two bodies in the dawn sky. I also managed a shot of Jupiter showing three of its large moons and a hint of a cloud belt!
