Description
You can plot the position of the Sun for the time-value that the program is currently using, as set in the 'Date Time' tab-page of the 'Settings Menu'. This may be the current time (recommended), or a fixed value, an offset value, or a loop between specified limits. You can choose to show the Sun position, and also the track of the Sun for the current date, and also the Sun-Analemma, which marks the position of the Sun over 365 days for the current Time. It is interesting to turn on the 'Base Lines' map-layer, and see how the Analemma is positioned between the Tropics of Cancer and Capricorn, and note how the sun moves up and down the Analemma over the period of a year.
The 'Sun Tracker' Map Layer is a Vector Layer composed of Points, Lines, and Labels, so the Style for each of these can be changed as desired by opening the 'Layers Menu', clicking the wanted layer on the left, then clicking the relevant panel controls on the right.
The 'Point' controls the display of the Sun icon. You can adjust its size by changing the Point Size, and its color by changing the Point color.
The 'Lines' control the display of both the Sun Track and the Sun Analemma, with settings for color and line-width available. You can control if the Sun Track and the Sun Analemma are shown with the Layer Features.
The 'Labels' controls the label that is shown adjacent to the Sun. It shows the current Sun position in degrees over the earth's surface.
