SolarView



Application SolarView is a mobile application (Symbian 3rd Edition), which calculates fascinating and useful sun-related information based on the given location coordinates and current time. SolarView is basically an abbreviated, pocket Astronomical Almanac. Among other things, SolarView can give exact sunrise- and sunset times at any location on earth at any time in the past or future. This information is presented in both graphical and text format.

Opening View

When the application is started, the Opening View is shown. The Opening View includes a background picture with the sun and the Earth.

At the bottom of the screen the given location coordinates, sunrise- and sunset time and current time are displayed.


Features Traditionally, sunrise, sunset and noontimes are obtained from Astronomical Almanacs, but these give values only for certain localities. To obtain values for other places, the user has had to perform his/her own calculations. Even within a single time zone, sunrise- and sunset times, and noontime, vary significantly depending on the observer's location. However, SolarView gives exact sunrise- and sunset times anywhere around the globe.

For example, SolarView answers the following questions:

- At what time will the sun rise and set today at my current location?
- What is the current position (altitude, azimuth) of the sun?- How many hours will the sun be above the horizon today, at what altitude will it shine at its highest and at what time (noontime)?
- At what location on Earth is the sun at its zenith now (shining directly above)?
- What is the distance between the Earth and the sun right now?

The SolarView application has two modes: real-time mode and simulation mode. In real-time mode, SolarView recalculates the data every 30 seconds; for example the position of the sun in the sky is updated every 30 seconds. In simulation mode, the user can move forwards and backwards in time using the arrow keys. In this way, he or she can define the observation time. Whenever the observation time changes, SolarView immediately recalculates the data and presents it on screen.




Use cases Use case #1: You plan a holiday to some sunny destination in three months' time, and want to know the exact sunrise and sunset times on your hotel's balcony, and how high the sun will climb by midday.
Solution #1: Find the geographical coordinates of your hotel, for example by using Google maps, Nokia Maps or by some other means. Start the SolarView application and enter the hotel's coordinates, open the Sun Position view, switch to simulation mode and use the arrow keys to change the observation time to the first day of your holiday.

Use case #2: You want to check what time the sun will rise and set at your summer cottage on 21st June (summer solstice) and 21st of December (winter solstice) and at what altitude it shines at noon.
Solution #2: The solution is the same as in use case #1, except that you use your summer cottage's geographical coordinates.

Use case #3: You want to know for how many hours the sun will remain above the horizon at your current location today, and at what time darkness will fall.
Solution #3: Open the SolarView application; use the GPS receiver (built-in or separate module) to obtain the coordinates of your current location. In the Info Sheet view, you can read the time at which the sun will set and that at which twilight will end and the hours of darkness begin.
