Hi,
After the success of SolarSystemScope we have launched a new Watch & Play model
http://www.sunmoonscope.com/
focused on the Sun and the Moon as they appear from the given location of the Earth surface:
- current position of the Sun, its trajectory, time and azimuth of sunrise and sunset
- moon phases, current position and trajectory of the Moon
- seasons, solstices and equinoxes in chart
But the most interesting part is to drag the model in time and watch changes during a day or year.
(polar day and night, analemma and situations on the equator are our favourite)
Enjoy it :-)
