SunCalc at the Hardknott Roman Fort
As told by its owner (Vladimir Agafonkin), SunCalc is an app that shows sun movement and sunlight phases during the given day at the given location, where we can see sun positions at sunrise, specified time and sunset. A thin orange curve is the current sun trajectory, and the yellow area around is the variation of sun trajectories during the year. The closer a point is to the center, the higher is the sun above the horizon.
Here an example: SunCalc at the hardkontt Roman Fort
