June 21, 2019. The summer solstice. It’s the longest day of the year, marking the start of summer. That day, the Northern Hemisphere is closest to the sun in earth’s orbit. In Arizona, the sun will rise at 5:18am and set at 7:38pm — a day length of 14 hours, 20 minutes.
In the Southern Hemisphere, it’s the shortest day of the year.
The ancient monument Stonehenge is closely associated with the summer solstice because on that day the sun rises directly in the center of the four great stones known as the Heel Stone.
At the prehistoric Pueblo Grande ruin in central Phoenix, there is a mound believed to have once held an observatory whose door, aligned with Papago Park’s Hole in the Rock on the summer solstice.
Phoenix’s Burton Barr Library, located at 1221 N. Central Ave., celebrates the solstice each year. Library architect Will Bruder designed a special feature to mark the event. At the top floor of the library, when the sun reaches its highest point in the sky, it illuminates special skylights and columns that appear to become lighted and send cascading shadows down the walls. This year’s event takes place from 11am to 1:30pm. Live music begins at 11:30am, followed by a presentation. Visitors can get a solstice-themed keepsake printed on the library’s 125-year-old printing press.
