Sun Tracker Instructions

• Click on the "Launch Tracker" Button below to start.
• The top half of the display is your control console:
  1. Choose the month and day you desire using the pull-down
     menu and the clickable arrows.

  2. Choose the location you want in one of 3 ways:
     • Picking a city from the pull-down menu
     • Clicking a location on the world map
     • Entering in the longitude and latitude

  3. Click "Run" when you've made your choices

• The path of the sun at this place and on this day is traced on both the bottom panels.
  • For the left display, imagine that you are standing looking
    South, and the surrounding circular view has been snipped
    through the North and laid flat.
  • On the right, imagine that you are the stick figure with the diamond head. The path of the Sun is traced on the imaginery
    celestial sphere that surrounds you like a dome. This trace is exactly what you would see if you were using Dr. Leila's
    celestial sphere tool.
  • Click on the sphere and drag it around to get a better view!

• Choose another place or date and click "Run" again to get another plot.
• When you have too many plots and want to clear your display, click "Reset".
