Twilight's last gleaming

I was able to catch the sun setting over the far ridge.  This is one of those photos that really needs to be seen enlarged before it looks decent.

  1. Does the last gleaming occur after the gloaming? Serious question.

  2. Gorgeous! It's almost worth waiting a whole day for that moment.

  3. My Oxford English Dictionary says that gloaming meant 'evening twilight' around 1000. The first citation for 'morning twilight' is 1873. And 'shade or dusky light' was cited in 1832.

    As an amateur astronomer, and very amateur sailor, I know that there are degrees of twilight. Civil twilight begins at the moment the sun sets and ends when it's too dark to work outside :-) In lots of places, this is 30 minutes after sunset but it can be strictly defined as the moment the Sun has sunk 6 degrees below the horizon.

    At that point, nautical twilight begins. Nautical twilight lasts until the horizon blends the sea and sky. This is strictly another 6 degrees.

    Astronomical twilight is that time when the horizon is noticeably brighter than the zenith, making it hard to see faint celestial objects near the horizon. This is another 6 degrees.

    I don't honestly know if there is a difference between gloaming and civil twilight. But I'm going to do some more searching!
