Determine the latitude of the tangent rays of the Sun in the Northern Hemisphere on the following days of the year, then indicate if latitudes north of the tangent rays in the Northern Hemisphere are receiving 24 hours of daylight or 24 hours of darkness. Remember, the tangent rays and circle of illumination will be the same number of degrees of latitude away from the North Pole as the declination of the Sun is from the equator. If the declination of the Sun is north of the equator, it is the high-Sun season (“summer”) in the Northern Hemisphere; if the declination of the Sun is south of the equator, it is the low-Sun season (“winter”).
