What Does BMNT Stand For?

BMNT stands for Begin Morning Nautical Twilight

BMNT, or Begin Morning Nautical Twilight, refers to the specific time in the morning when the center of the sun is 12 degrees below the horizon. During this period, there is enough natural light for activities to commence without artificial illumination, and navigational stars become visible for maritime navigation. BMNT is an important consideration for sailors, aviators, and outdoor enthusiasts who rely on twilight conditions for visibility and safety in their operations.
