A crystal clear Moon is moving upwards, left to right, across the night sky – seen through the glass roof of our kitchen. Last night, it was a Blue Moon, which I needed to have explained to me again. Elaine and I watched the Moon through the binoculars a few moments ago, marvelling at the sheer number of impact craters. An indication of what a hell the Earth must have been in its early days. I recall seeing a huge circular impact crater somewhere as I flew east across Europe many years ago – and another in the south-west of the USA.
