Total Solar Eclipse

For the week of August 13, 2017

Excitement is building for a total solar eclipse on August 21. It’s been 99 years since a total solar eclipse has swept the width of the United States. So it’s no surprise that scientists and many other folks are eagerly anticipating this rare event. This week, learn how to best prepare for the coming solar eclipse.

Guest: Lindsay Glesener, Assistant Professor in the School of Physics & Astronomy at the University of Minnesota

    Part 1
    During the total solar eclipse, the moon perfectly covers up the visible disc of the sun (the bright spot), so scientists can observe the outer ring, the corona, much more easily, says Glesener. The path of totality runs from Oregon to South Carolina; though Minnesota will see only a partial solar eclipse with the moon coving between 80 and 90 percent of the sun, Glesener says the event will still be worth viewing. For those who do want to see the eclipse, it is important to have the proper eye protection.
  • Part 2 – 12:10

    Part 2
    Citizen scientists can help with solar research during the eclipse. One project Glesener points to is the Mega Movie—an effort to combine photographs of the eclipse along the line of totality for continuous datasets. More information at: eclipsemega.movie/megamovie

    The University of Minnesota is throwing a Pre-Eclipse Block party on August 13 at 12 pm at the Physics and Nanotechnology Building. Learn more about the eclipse and pick up a pair of solar viewing glasses (while supplies last). More information about the event can be found at: events.umn.edu
