It's time for the semi-annual update of the Chicago sunrise chart. (You can get one for your own location at http://www.wx-now.com/Sunrise/SunriseChart.aspx.) I'm a little late with the mid-year update because I've been a little busy. You haven't missed much—and anyway, they overlap.
An interesting note about 2010: the sunset on November 6th will be the latest sunrise in Chicago (7:30am) until 2021—and that, only within 4 seconds of precision.
