Not knowing the exact direction to the north (only rough direction) and the path by which the Sun will move across the sky, I selected the observing location at the beach that had the most unobstructed horizon in the northward way.
The whole sunset took more than half an hour. Truly, I did not expect for it to be so sluggish, and the angle between the horizon and path of the Sun to be so small. The most remarkable was a color of the Sun surface just before it completely set and when it begun to rise. It’s surface shone with a intense green color, probably due to large refraction differences at the horizon.
The Sun was actually bellow the horizon for just about 15 minutes. During that time there was no apparent visual change in the brightness of the sky.
