Here comes the sun.

Today's Ottawa Citizen has an article about solar radiation on this, the shortest day in the year. In Ottawa the day's length is down to its lowest of the year at 8 hours, 42 minutes and 49 seconds, But tomorrow will have a longer day by a grand total of four seconds. And the day's will get incrementally longer after that.

Today's sun will reach a peak elevation of 21.2 degrees above the horizon, a huge contrast to its angle of inclination of 68 degrees at the summer solstice. And the current solar radiation at 550 watts per meter will increase to 1240 watts. Summer is a coming in!

 I find this article fascinating while Anne calls it boring. There is a second article, about the number of fender benders and pedestrian injuries caused by falls during the freezing rain storm of yesterday. I feel the  article about the return of sunlight is much more uplifting.
