Civil Twilight times for today:

Morning Civil Twilight (MCT) and Evening Civil Twilight (ECT) are the times that air traffic (also road and sea traffic) switch between daytime and nighttime rules. They are defined as the time when the Sun is six degrees below the horizon at a particular location.

The times below are recalculated each day to the nearest minute of local time, for the Latitude / Longitude of each airfield. They will not precisely match the AIP times which are rounded as to location and day of year.

The 'VFR Daylight' is the elapsed time fom MCT to ECT.
