Cool Sun Facts · Your horizon
When does the Sun actually reach you?
Standard sunrise assumes a flat horizon. Enter the hills, trees and buildings around your spot, as angles above level in each direction, and see when the Sun really clears them. The profile is kept in this browser, against this place.

Measuring your skyline
- Stand where you want to know about. For each direction where something rises above the level horizon, note its bearing and how high its top looks.
- With your arm straight out, a little finger covers about 1° and an outstretched hand, thumb to little finger, about 25°. A clinometer app or a photo with a known field of view does better.
- Bearings here are from true north. A compass reads magnetic north, which differs by the local magnetic declination, and that changes with place and over time; a map is usually better.
- Measure the skyline, never the Sun. Looking at the Sun can harm your eyes.
