Summer will officially arrive on Friday in what is known as the Summer Solstice.
At 10:42 p.m. EDT on June 20 (0242 GMT on June 21), the sun will reach that point where it is farthest north of the celestial equator. To be more precise, when the solstice occurs the sun will appear to be shining directly overhead for a point on the Tropic of Cancer (latitude 23.5 degrees north) in the western Pacific Ocean, roughly 1,400 statute miles (890 km) to the south of Tokyo, Japan.
