Actually, the sense of a twilight here doesn't really exist at this latitude - when the goes down it's dark in 30 minutes.
Whereas, this time of the year [a month prior/after the summer solstice] at higher latitudes is where you'll find that eerie feeling a "twilight" during dusk.
Also locales closer to the equator [within 20 degrees] the sun moves quicker, because of the angle of the earth, and the ratio of day/night is somewhat equal. Those more distant latitudes is where the sun lingers slowly across the sky - creating much longer days and of course this extension of twilight.
