Today, this morning (at 03:19am to be exact), the moon became "full" (exactly 100% - despite appearing to be 100% to us here in the UK for at least a night or so previous) and as this is the full moon nearest to the Autumnal equinox (a week ago here in Blighty, this year) - traditionally it is known as the "Harvest moon".
The Harvest moon doesn't always fall in September - if the nearest full moon to the Autumnal equinox falls in early October - THAT is the "Harvest moon" (although this cannot be later than 11th October). This happens about once every four years in the northern hemisphere.
Now...If the "Harvest moon" rises on the same night as the Autumnal equinox night (i.e. Autumn begins with a full moon) - this moon wouldn't just be called a "Harvest moon".... no..... it would be a "Super Harvest moon".
This last happened two years ago (September 23rd 2010 - previous to that it happened in 1991) and it just so happened that the "Super harvest moon" rose in a part of the sky that Jupiter happened to rise in also - of course I had to try and get a shot. That is the photo reproduced here and below.
The next "Super Harvest moon" (a full moon rising on the first day of Autumn in the north) won't occur for another 17 years (2029) so if you missed it two years ago, you have a wee wait yet...
