Hello navigators,
Attached the terminator of the Sun around the spring equinox and summer solstice, (plotted under Google Maps projection with my App AstroNavigation).
Circle of equal altitude - Wikipedia - Circunferencia de alturas iguales - Wikipedia, la enciclopedia libre
Special cases of CoP:
- Parallel of latitude by Polaris altitude.
- Parallel of latitude by altitude of the sun at noon, or meridian altitude.
- Meridian of longitude known the time and latitude.
- Circle of illumination or terminator
Fair winds!
