shining directly down on the Tropic of Capricorn — latitude 23.43-degrees south — at 10:27 p.m. Eastern Time. At that moment, if you were located in Western Australia at a point near Lake MacKay, the sun will be shining directly overhead and its six-month southward migration will come to an end, marking the beginning of summer for the Southern Hemisphere.
Sun rides high ... and low
A tradition was established
Longer ... but colder days
Starting tomorrow, the length of daylight will begin to increase — imperceptibly at first, but a month from now, it will become obvious that the sun is rising earlier and setting later. Yet, there is an old saying: "As the days grow longer, the cold grows stronger." If the insolation — the total energy received from the sun — alone governed the temperature, we should now be experiencing the year's coldest weather.
