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 need to be able to judge the moon’s phase, but if you are trying to use the ‘phase method’ of finding direction from the moon then it is vital. I go into a lot of detail of this method in the book, because it is very satisfying but no less challenging. In…

I’m just back from giving a short talk at the Royal Institute of Navigation‘s Land Conference at the National Physical Laboratory.
I learnt plenty from the other speakers and chats during the breaks. One little gem: the Apollo program nearly lost two astronauts, literally. They were roaming the lunar surface and became temporarily unaware where ‘home’ was. Without a map, compass, GPS or any other instrument there were some tense moments before they found their way back successfully. Definitely an opportunity for some natural navigation training in this niche market, as I was not too shy to point out to the assembled!
Something that makes a walk on the moon more challenging than on earth is that the moon has a much smaller radius and therefore has a more dramatically curved surface, the result being you cannot see nearly as far on the moon as you can on…
