Illustration of the solar angles: (a) altitude angle, ; (b) azimuthal angle, . The solar path corresponds to a day in the early fall or late winter seasons in the northern hemisphere, that is, just prior to the spring equinox or just after the fall equinox. Solar noon is the time of day when degree, that is, the sun is directly at south and is halfway between sunrise and sunset.
