Happy Solstice!

Today is the longest* day of the year, unless you're south of the equator where it's the shortest day of the year. The Daylight Map illustrates this well. The bands of darkness get wider as you travel south. The areas north of the dark band are in 24 hour daylight. City lights from NASA's Visible Earth are shown in the areas where it is dark.

Here's a close up of the sun setting over the Eastern Cape Province of South Africa.

 The site also has a Cloud Map, with semi-real time cloud cover overlaid on the same image.

* it's not really any longer, there's just more hours of daylight.
