Astronomical Darkness puts valuable information about the coming night at your fingertips! These can be useful for star gazers, serious astronomers, night time photographers, hunters and vampires. As a dedicated deep sky observer, you are probably planning your next session according to astronomical darkness and absence of the moon.  

The widget’s view is centered on the coming night, so the „new night“ starts at 12:00, noon! As a result of this, moon times may differ from your planetarium app, which always relate to the current day (0:00-24:00). 

The outer circle is the sun-circle. It displays the time, that the sun is above the horizon, sunrise and sunset, civil-, nautical- and astronomical dusk and dawn and darkness on a 24 hour scale. Inside the the sun-circle, the moon-circle is drawn. Light-gray indicates the times when the moon is above the horizon. All times are accurate within 5 minutes.

With the up and down botton or a tap on the upper or lower half, you can change the date. When on current date, an indicator for current time is displayed. In addition to date and location used for calculations, the moon phase and illumination are displayed. Finally, times without sun and true astronomical darkness are available.

*Coordinate Colors*
Green: Got coordinates from the last activity
Yellow: Got coordinates from the latest weather report (Weather reports are usually provided for bigger cities. If you use this widget in a non urban area a GPS location is better)
Red: Using same cooridinates as last time.

If you want *really accurate coorinates/ times* press the 'start' button to activate the GPS.

Your watch will vibrate to indicate GPS startup and another time if a good GPS position was calculated.
