Lunatic

✕

A 24-hour solar clock. The one hand goes round once a day: solar noon, when the sun is highest where you are, is at the top, and solar midnight is at the bottom. The hour markers round the rim are ordinary clock time, so the 12 sits wherever clock noon falls that day, and the small dot on the rim is the minute, :00 at the 12.

The face

• Day — sun above the horizon, from sunrise to sunset.
• Civil twilight — sun 0° to 6° below the horizon. Bright enough to see by.
• Nautical twilight — 6° to 12° below. Horizon still visible, brighter stars out.
• Astronomical twilight — 12° to 18° below. Sky not yet fully dark.
• Night — sun more than 18° down. Stars, and the moon with today's phase.

Ticks inside the face mark sunrise, sunset, solar noon and the half-way points of the morning and afternoon. Tap the clock to show or hide the time and this line.
