Day 166: Winter Solstice
In Australia we are under a week away from the winter Solstice...June 21. This is apparent from the shorter daylight hours. Fitting a walk in for Toby is proving a challenge as it is dark by 5.30pm. Much to Toby's delight, today was an exception.
The winter solstice occurs at the instant when the Sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere. The seasonal significance of the winter solstice is in the reversal of the gradually lengthening nights and shortening days. Depending on the shift of the calendar, the winter solstice occurs some time between June 20 and June 21 in the southern hemisphere, during either the shortest day or longest night of the year.
