Tyrrhenian Sea and Solstice Sky
Explanation: Today the
solstice occurs at 23:03
Universal Time, the Sun reaching its southernmost
declination in planet
Earth's sky. Of course, the
December solstice marks
the beginning of winter in the northern hemisphere and summer in the south. When viewed from northern latitudes, and as shown in the above horizontally
compressed image, the Sun will make its
lowest arc through the sky along the southern horizon. So in the north, the
solstice day has the shortest length of time between sunrise and sunset and fewest hours of daylight.
This striking composite image follows the Sun's path through the December solstice day of 2005 in a beautiful blue sky, looking down the
Tyrrhenian Sea coast from Santa Severa toward Fiumicino,
Italy. The
view covers about 115 degrees in 43 separate, well-planned exposures from sunrise to sunset.
