The Moon is waxing at the moment. That's an old fashioned term that means that the Moon is getting more and more lit up as the days go by. I posted about the first crescent last Thursday. Technically the New Moon is when you can't see anything I think. Today we have reached the first quarter. Oddly named because half of the face is lit up.
The New Moon coincided with awful flooding on the east coast - a tidal surge. At the New Moon, the Moon and Sun are in line on the same side of the Earth. They pull together on the sea and produce bigger tides. This coincided with a major storm to cause flooding.
