On 21st June, the Sun  (UPSC CSE 2019)

1. does not set below the horizon at the Arctic Circle
2. does not set below the horizon at Antarctic Circle
3. shines vertically overhead at noon on the Equator
4. shines vertically overhead at the Tropic of Capricorn

Answer: A

Explanation: 

On the June/Summer solstice (June 21), the Earth’s North Pole is at its maximum tilt towards the sun. At this time, the sun appears directly overhead at 23.5 degrees north latitude, along the Tropic of Cancer (and not Tropic of Capricorn). The June solstice marks the year’s northernmost sunset and sunrise. It brings the year’s longest period of daylight to the Northern Hemisphere (least daylight in the Southern Hemisphere). Around the Arctic Circle, the location of sunrise and sunset starts to converge in the northern sky, until eventually the sun never sinks below the horizon. North of the Arctic Circle, the sun neither rises nor sets but stays above the horizon continuously, around the clock.
