Happy Equinox!

There is not really an equal amount of day and night, though. Because twilight. (The picture represents how wide a band twilight really is).

Kind of an interesting article. Apparently, there are two types of twilight. Civil twilight is when the sun is 6 degrees or less below the horizon and you can carry on doing normal daylight things. Nautical twilight is when the sea becomes difficult to make out, usually when the sun is 12 degrees below the horizon. At 18 degrees below the horizon, it am dark.

Also, it isn’t really dark six months of the year at the poles. Because twilight.

Oh, and people? Summer’s gone. Bend over!
