THE NIGHT SKY : October, a month of two moons
THERE will be two full moons this month; one on the 1st and the other on the 31st. This second one is referred to nowadays as a ‘Blue Moon’. The Moon takes around 29.5 days to orbit the Earth once and apart from February all months have either 30 or 31 days, meaning it is possible to have two full moons in a calendar month.
