If I look up the weather at EGLF
here I also get sunrise and sunset.
Today the times are
Sunrise - 7:23 (the time the sun appears above the horizon)
Civil twilight 6:49 (It is bright enough to see the horizon and due normal work without lights after this time)
Nautical twilight 6:09 (The sun rises to within 12 degrees of the horizon - it is pretty dark before this and hence counts as nights for takeoff and landing)
Astronomical twilight was 5:31 (It is proper pitch dark before this)
