Technical Notes:
The sunrise, transit and sunset calculations implement the algorithm described in:

Solar Position Algorithm for Solar Radiation Applications
(Technical Report NREL/TP-560-34302, Revised January 2008) by Ibrahim Reda and Afshin Andreas, based on the algorithm described by Jean Meeus.

Limitations:
• Requires an Internet connection for full functionality
• Accuracy reduces around the polar regions
• Auto-rotation requires a hardware compatible device
• More features will be coming, so give us feedback...
