Happy Easter! When is Easter? Today, is the short and not very helpful answer. The longer, more useful answer is: Easter is always the first Sunday after the first full moon after the vernal equinox. This explains why it is never the same from year to year. The calendar date of the equinox will only move by a day or so, but the timing of the next full moon can vary by as much as 29 days. There is an interesting page about the history of this calculation on this page.

Just managed to snap the 'supermoon' as it rose above the woodland to the east of me. This photo was taken tonight at 19.03 GMT. Tonight's moon is the first time that a full moon has coincided with perigee, that is the moment when the moon is closest in its orbit, for 18 years. This is no ordinary perigee either, the moon will be 30,000 miles closer to Earth than usual. The result is what has been nicknamed a 'supermoon'. The best time to appreciate its enlarged size is when it is close to your horizon, rising…

I have just been watching a beautiful full moon rising above the trees in the east. It was shrouded in layers of cirrostratus for a few minutes, but then rose above them. In winter full moons rise north of east, in summer they rise south of east. They rise further from east the nearer we get to the solstices. The full moon always behaves in the opposite way to the sun, in time and direction, as it is opposite the sun in its cycle.

Another very enjoyable Beginner's Guide to Natural Navigation course at West Dean College on Saturday. There were sailors, walkers, a forager and an army officer among the ever-varied student backgrounds. My thanks to all for coming. Last night, shortly after 10.30, I took this photograph of the moon rising above the woods and emerging from behind thin clouds. It looks very much like a full moon, but is actually one day after full, a waning moon. It does highlight the difficulty of judging the phase of the moon accurately. From an aesthetic perspective there is no…

Another very enjoyable Beginner's Guide to Natural Navigation course at the Royal Geographical Society yesterday. The diversity of interests and experiences never fails to amaze me; from desert wanderers to cruise ship sailors and even a sailor from a tall ship in the Pacific. Wonderful!It was a beautiful full moon last night and I got to experiment with a new lens that I have bought. Still a long way to go until I take a photo of the moon that I am happy with, but always learning which is satisfying.The phase of the moon appears the same all over…

The title of this post is not, for once at least, a reference to my style of blog-writing, but to the BBC Radio 4 program hosted by Clare Balding.On Wednesday night I joined Clare and the Ramblings team for a walk on the South Downs Way; we headed west from Amberley, finishing at the Bignor Hill car park. We were treated to stars, planets and a full moon. I'll let you know when it is airing, but should be sometime in June.I felt hugely privileged and honoured throughout the walk, as early on Clare revealed that she has been embarking…

If you are feeling peculiar then it is probably best not to venture outside tonight. The gravitational pull of the full moon's alignment with the sun might have strange effects as it pulls on the water in your brain. Or so the ancients believed.Alternately, you might want to do something that GPS users would see as a symptom of madness and use it to find east in the early evening, south at midnight and west before dawn.I took this photo about ten minutes ago (18.23 GMT), looking east.

This is the full moon from two nights ago, rising amongst the clouds. The picture was taken at about 11 o' clock and so we are looking close to southeast.
