Tonight we will have a blue moon rising at 8.32 pm.Sorry to disappoint; – it is not actually blue, but I couldn’t resist the picture!
The term ‘blue moon’ is used to describe the second full moon in a calendar month. The previous full moon was on July 2nd, hence, tonight’s is ‘blue’.
This definition is quite a new one, apparently a ‘blue moon’ was originally the 3rd of four in a season. Most years there are 3 full moons in a season; spring, summer, autumn and winter, however, occasionally there are four and when that happens, the 3rd (not the 4th) full moon is classed ‘blue’. The newer and easier to detect definition originally came about through a mistake but has been widely accepted. However, as is the way of these things there is confusion and disagreement!
The next blue moon by the monthly method is on January 31st 2018 and by the seasonal method is May 21st 2016. So what out of the ordinary thing shall we do today?
Astrologically the moon is in Aquarius the sign of the new and different suggesting an opportunity for breakthrough and change, particularity in our wider society. I’m going to have a look for the moon, last night it was lovely, as we had a clear evening sky in Norfolk after all that rain in the day.
Happy moon watching!
