Click asks your browser for a one-time fix: no request happens on page load.

Your browser asks once, on your click; the coordinates stay in this tab's memory, feed only the local astronomy math, and are dropped when you press Clear or close the tab. Nothing is stored or sent.

- SunCalc 2.0.1 (BSD-2-Clause) computes the position: Meeus/NOAA-derived geometry, the same engine behind every other sky tool here.
- Azimuth is degrees clockwise from true north; altitude is apparent (geometric plus refraction), about a minute of accuracy inside 1900-2100, and dates outside that range are refused.
- Your wall-clock time resolves through the zoned-time engine: DST gaps take the later edge, folds the earlier. The instant used is printed in the table.
- The shadow ratio is flat-ground geometry (1 / tan altitude); terrain and obstacles shift what you actually see.
