The Geochron

Today is the summer solstice (at least up here in the Northern Hemisphere). In lieu of heading to Stonehenge, I'm celebrating with my Geochron. At least we're free of druids and pagans, here. I think.

The solstice is a particularly interesting day to see which areas of the world are receiving the maximum and minimum amount of sunlight. Thank God for the Geochron! Or thank James Kilburg, the Geochron's inventor.

The thing I love about the Geochron is that it shows the exact portions of the world that are in daylight and darkness at that very moment. Looking at the Geochron today, you can see how much more sunlight the Northern Hemisphere is getting compared to the Southern Hemisphere. It's nearly midnight in Iceland, and it's still light, and the sun is just rising in other parts of Scandinavia. The sun has set on nearly all of South America, but North America is still bathed in light.

The Geochron has another great feature showing the part of the Earth that the sun is directly above. Today, it's directly on the Tropic of Cancer. Unfortunately, for us up north it's now on its journey back toward the Tropic of Capricorn.
