You know the drill: Click for larger. This is the Sun's motion from rise to set on 21 December 2007. The Winter Solstice is the shortest day of the year in the Northern Hemisphere, the day Winter begins. The photo looks out over the Tyrrhenian Sea on the coast of Italy from Santa Severa toward Fiumicino.
PizzaQ (1 slice plain): I count 40 exposures. How long did the Sun take to travel from Sunrise to Sunset above Italy on the Winter Solstice -- and so how much time elapsed between two consecutive exposures?
In the Southern Hemisphere, this is the day Summer begins, and is the longest day of the year.
