Sun Board App

Documentation

These will make the Sun Board application much more useful for you:

Lock:

On the top left, there is an image of a lock. Press this, it will lock the rotations. This should cover your last point.

Sun Dial:

You may not be able to see all the lines on the dial in the first place. If not, then enable them in the SETTINGS menu. Press MENU then Settings and enable: Draw solstices, Draw hours's dial (second and third options)

  • The Green arc is todays sunrise and sunset sun azimuths
  • The Red arc is the sun's azimuth on the day of the summer solstice (it marks the winter solstice in the south hemisphere).
  • The Magenta arc is the sun's azimuth on the day of the winter solstice (it marks the summer solstice in the south hemisphere).
  • There are some small lines on the Green arc. Each line is one hour apart from the other and mark the sun's azimuth at the given time. The taller ones mark a three hour mark (9, 12, 15, 18, etc). One of the tall ones is marked red. This is 12 o'clock.
  • The yellow line marks the current sun's position
  • Finally, the orange dashed lines mark the suns position at the civil nautical and astronomical twilights, respectively. This corresponds to an elevation of -6, -12 and -18 degrees, and it actually tells you when it is dark outside. Also, if you are into photography, this shows you the golden hour of the day (or the magic hours as may call it)

Other stuff:

In the main screen, press MENU then Legend. You will be given a list of terms and their definitions. Also links to wikipedia are provided.
