2017 Total Solar Eclipse

Notes and Instructions on the 2017 Eclipse Map

  • After the program boots up, use your zoom function to zoom into the eclipse path.
  • Note that there is a blue line in the middle of the shaded area. The blue line is the center-line of longest totality. As you move North or South of the blue line, the totality is shorter.
  • The pink colored lines that border the shaded area is where totality ends and you will see a partial eclipse. 
  • As you move your cursor, in the upper left hand corner, you will see exact terrestrial GPS coordinates.
  • Left-click on any location, and you will have complete information about the eclipse at that exact spot including start and stop times of totality. 
  • Click on the blue Help link in the upper right hand corner of any pop-up for more information about all the great things this program can do for you.
