The natural Navigation: The Right Course, Naturally

It would be true to say that I would not be writing this blog if the sun rose in the same place each day. I don’t mean that in a very general sense, it’s not because the whole world would be very different and maybe the dinosaurs would have survived and humans would never have evolved, blah, blah…

No, it is because in the spring of 2008 I was busy trying to work out whether there was any point in trying to make a living by teaching natural navigation, or not. Whether, perhaps, that was the stupidest idea I had ever had, a competition with some depth in the field. The problem was that there was no ‘sensible’ way of deciding whether to go ahead with it or not. There was no point bouncing the idea off family, bank managers, priests or ouija boards. The answers that would come back…

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 or setting. Since it is a full moon this will be close to the time of your sunset and then sunrise.

There are some fascinating musings in todays Telegraph about any possible influence of this supermoon on tectonic activity, of greatest interest of course: earthquakes.

A belated thank you to everyone who came to my talk at the Marine Studios in Margate a week ago, and another thanks to those who also bought a book afterwards.

I arrived an hour early and walked down to the beautiful beach and went for a swim (yes that really is it in the photo). I then dried myself off in the beach car park, with the car radio on as I listened to Andy Murray losing, valiantly, to Rafael Nadal. A more British experience would be hard to imagine. I walked up to the Studios to give the talk, watching a kid go beserk after dropping an ice cream and feeling the sand between my toes.

Whilst very vaguely on the subject of swimming, the Independent invited me to be on their Best 50 swimming spots in the UK panel. The results can be found here.

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…

My thanks to everyone who came to my talk last night at the Weald and Downland Museum. What a wonderful place to spend a summer’s evening, I recommend a visit to anyone who has yet to sample its delights.

On a different note, I received a fascinating letter recently from someone who has read the book. They wrote to me with an unusual observation.

I have touched the phenomenon of the ‘green flash’ at sunset in this blog and elsewhere, it is well documented and well heard-of. My correspondent is keen to learn more about something different and since I have been unable to solve the mystery, I promised to publish the extract from his letter here in the hope that a blog reader may be able to offer an insight.

“...My second point is the green flash you mention. My experience was quite different from the quick…

Last night I managed to take 46 photographs in a desperate bid to catch the elusive, and some like to say mythical, ‘green flash’ at the moment of sunset. The green flash is an optical phenomenon caused mainly by blue/green light bending more than the reds/yellows. There is a fuller description of its causes on Wikipedia.

I did not manage to see or capture the flash, but peering out across the Persian Gulf at the anchored ships, feeling the cool westerlies coming off its waters as the heat of the day faded… is not a bad way to endure a fruitless search.

It is often very difficult to see the sun clearly at the moment of sunset due to clouds or haze, but there are times when, if the sky is clear, the air is dry enough and the horizon is an ocean, then the sun can be seen…

‘Courting bustards’ is not an excellent new profanity, something that would sound good with rasping voice and sent in the general direction of a parking warden putting a ticket on your car, it is actually a reference to the romantic habits of the male great bustard bird.

Researchers from the IE University School of Biology in Santa Cruz, Spain, have found that the male bustards align themselves with the sun when trying to attract a female. Their white feathers, the bustard’s equivalent of an Armani suit/Ferrari/pair of Reeboks – delete as applicable, show up better when aligned to catch the sun’s rays. Dr Tommaso Pizzari, an ornithologist from Oxford University, observed that although it made the birds more vulnerable to predators, it certainly made them more visible to females. ‘That’s why we think these puzzling traits evolved and are specific to males.’

Although the bustards have been found to do…

I went for a walk in the South Downs yesterday afternoon. The air was cold, there were still chunks of ice lining the north-facing side of chalk ruts in the path. The sun was up for the first part of the walk and made direction-finding easy. When it fell below the hills to my southwest it gave different opportunities. One of my favourite dusk techniques is to use the light reflections of cloud edges to gauge where the sun must be behind higher ground. This photograph from 4.30pm yesterday shows this effect quite clearly. The sun is reaching the far ground, trees and clouds, but it does not light the clouds equally. The bright edges act almost as a parabola, pointing the way back to a now invisible sun.

The picture was taken looking northeast. The very perceptive will have noticed that there are molehills in the foreground and that…

…from the Scottish Highlands.

Yesterday afternoon I threw the snow off the Land Rover and headed out into the white – I had about half-a-dozen minor outstanding ‘to-do’s for the book, but there is no point writing a book about natural navigation if you are the sort of person who can resist these conditions. Dressed in a suitably ridiculous balaclava I made my way to the foot of Halnaker Hill and then proceeded uphill in wellies. Unless I’m on a mountain I find wellington boots with two pairs of socks the ideal footwear for small excursions in snow, even good hill-walking boots let some moisture in eventually, but wellies do at least stay dry even if it means slipping about a bit in places.

A roe deer jumped across the path in front of me as I climbed the hill and there was the red breast of a robin waiting on the branch…
