Why does it work worse in higher latitudes and closer to dawn and dusk?
The shadow of the tip of the stick will always move in a straight line from east to west right?
At high latitudes I could imagine the shadow gets so long that finding the tip might become hard.
Around dawn and dusk, what is the problem? Does the shadow become too faint? Does the shadow move to slow to give a big difference in position?
- Sardtok 4y agoAt dawn and dusk, aka twilight, the sun is below the horizon. So you only get indirect illumination. Contrast is terrible, and shadows will be diffuse. The direction should still be mostly right, but you will be hard pressed to define the end of the shadow. The position of the sun can be a bit weird depending on the season the further away from the equator you are. Especially in the periods where the sun never rises above the horizon. Other than that I don't know exactly what problems you might have. The midnight sun perhaps flips the direction?
