Summer Solstice 2007

(Another recycled post. This one ran here.)

Today marks the Summer Solstice. Wikipedia provides this explanation:

"The summer solstice is an astronomical term regarding the position of the sun in relation to the celestial equator. At the time of the summer solstice, Earth is at a point in its orbit where one hemisphere is most tilted towards the sun, causing the sun to appear at 23.45 degrees above the celestial equator, thus making its highest path across the sky. The summer solstice is the day of the year with the longest daylight period and hence the shortest night. This day usually occurs on June 21/June 22 in the northern hemisphere and on December 21/December 22 in the southern hemisphere. The actual date changes due to differences between the calendar year and the tropical year."

I have been rather fond of the day for years, primarily because it marks the beginning of summer. Summer is easily my favorite season, especially early in the summer. There is something about early summer that just makes me smile. Maybe it is because it is filled with so much potential.

I also find the summer solstice to be interesting because of Stonehenge.

"Stonehenge (stōn'hĕnj') , group of standing stones on Salisbury Plain, Wiltshire, S England. Preeminent among megalithic monuments in the British Isles, it is similar to an older and larger monument at Avebury. The great prehistoric structure is enclosed within a circular ditch 300 ft (91 m) in diameter, with a bank on the inner side, and is approached by a broad roadway called the Avenue. Within the circular trench the stones are arranged in four series: The outermost is a circle of sandstones about 13.5 ft (4.1 m) high connected by lintels; the second is a circle of bluestone menhirs; the third is horseshoe shaped; the innermost, ovoid. Within the ovoid lies the Altar Stone. The Heelstone is a great upright stone in the Avenue, northeast of the circle. It was at one time widely believed that Stonehenge was a druid temple, but this is contradicted by the fact that the druids probably did not arrive in Britain until c.250 B.C. In 1963 the American astronomer Gerald Hawkins theorized that Stonehenge was used as a huge astronomical instrument that could accurately measure solar and lunar movements as well as eclipses. "

I don't know about you, but there is something very cool about the place. I haven't been there, but it is on my list of places to visit.
