Today, Friday June 21 is the first day of summer. Officially set to begin at 10:54 am here in Houston, we’ve been experiencing summer heat for many weeks. Summer solstice takes place as one of the Earth’s poles has its maximum tilt towards the sun and the sun reaches its highest position in the sky, ensuring the longest period of daylight during the year. About 6 hours ago, thousands of people gathered at Stonehenge in the United Kingdom to greet the start of the longest day of the year. Stonehenge, located in Wiltshire England, is an ancient monument comprised of very large stones that aligns with the midsummer sunrise and the midwinter sunset. People have been observing and celebrating solstices there for a very long time. Enjoy the first official day of summer 2019.
