The June solstice

The June solstice is the moment the Sun reaches its northernmost point in the sky: the longest day of the year north of the Equator. The times above are worked out with astronomia, an implementation of Jean Meeus’s astronomical algorithms, and agree with the US Naval Observatory’s to within a minute.
