We had a full Moon tonight and the sky was clear so you could not have missed it if you were looking. We watched as it crawled up into the sky, changing colours from almost orange to yellow and then to white as dusk was falling. –Such a wonderful sight.
The Moon is full when it is completely illuminated as seen from the Earth. This occurs when the Moon is opposite to the Sun. The lunar month is 29-30 days so we have a full Moon about 12 times a year.
