How to learn to find north using moon phases? I'm looking for easy-to-remember rule of thumb, at best some simple graphic.
It's quite trivial by full moon. Since full moon is in direct opposition to the sun, at the midnight it will be exactly on south.
Some time ago someone have explained to me how to navigate when the moon is in other phase, using the term of C-shaped and D-shaped moon, with deviation from north at midnight depending on how C- or how D- was that phase. He have made a sketch on the sand. I should have made photo or drawing of it, but I haven't thought about it and now I have problems finding similar sketch or similar rule of the thumb in internet.
