Speaker Schedule:

  • 11:00 am - 11:15 am: "Welcome" - Don Ficken, St. Louis Eclipse Task Force Chair/Others

Description:  Welcome to attendees.

Description:  On August 21 this year there will be a total solar eclipse visible from a large swath of the U.S., and Missouri will have a front row seat. This is the first total solar eclipse to be seen from Missouri since 1869; the first over St Louis since 1442! Dr. Angela Speck, professor of astrophysics and director of astronomy at Mizzou, will explain why solar eclipses happen, what you can expect to see and how to observe this event safely

Description: With the approach of the 2017 total solar eclipse, NASA has made available a multitude of resources for understanding what is happening and maximizing your enjoyment of this celestial event. This talk will give an overview of resources from online events to simulations to hand-on activities.

  • 12:15 pm - 1:15 pm:  "Panel Discussion:  Emergency Management and Weather", Panel Moderator:  Karen Hargadine, Assistant Superintendent, Rockwood Schools 
    • Panelists:
      • Owen Hasson, Incident Management Coordinator, Missouri Department of Transportation
      • Jim Kramper, Warning Coordination Meteorologist, National Weather Service
      • Kate Struttman, Disaster Program Manager, Eastern Missouri Region of the American Red Cross
      • Michael Theimann, Coordinator of Emergency Management, PIO, Metro West Fire Protection District, St. Louis County, MO
      • Sgt Scott Roach, Supervisor, Highway Safety Unit, St. Louis County Policy

Description:  The August 21, 2017 Total Solar Eclipse is a certainty for North America but traffic is an unknown for travelers and weather could be a spoiler. This panel of experts will discuss our region’s response to traffic and safety concerns related to the eclipse and weather-related matters.

Description: On 21 August, 2017, twelve states in the continental United States will experience a total solar eclipse.  Although the entire U.S. will be able to see a partial eclipse, only those within the approximately 70-mile-wide path of totality will be able to see the fascinating and beautiful outer layer of the Sun's atmosphere, the corona.  This talk will describe features of our closest star, the Sun.  We will also discuss the cause of eclipses, what to expect when viewing an eclipse, and how to safely observe it.

  • 2:00 pm - 2:30 pm:  "Lights...Camera...Action - Shoot the Eclipse" - Mike Reynolds, Ph.D., Florida State College, Professor of Astronomy

Description: This year’s eclipse might become one of the most-photographed events in science, and perhaps even in history. Learn in this fast-paced overview some of the do’s and don’ts in photographing the eclipse and surroundings, from using your smartphone or tablet to taking those magazine-quality images through a digital single lens reflex (DSLR) and telephoto lens or telescope.

  • 2:30 pm - 3:00 pm:  "Safe Solar Observation and the Great American Eclipse" - Anna Green, Saint Louis Science Center, Planetarium Manager

Description:  We’ve all been told to never look directly at the Sun because it can blind us, but what about during a total Solar Eclipse? During this talk, learn about your eyes, safe solar observation, and how to best (and safely) enjoy the upcoming Great American Solar Eclipse on August 21, 2017!

Description:  This eclipse is called the Great American Eclipse because it will be so accessible to tens of millions of Americans. I'll take you a quick tour of the entire path with an emphasis on Missouri. Advice for seeking clear skies on eclipse day will be discussed as well as my best estimates of how many people will be visiting the St Louis area on eclipse day.

  • 3:30 pm - 4:00 pm:  "Edison and the Eclipse that Enlightened America" - David Baron, American-Eclipse, Journalist, Author, Publisher

Description:  On July 29, 1878, a total solar eclipse crossed America’s Wild West and lured many of the era’s great scientists to Colorado and Wyoming. Among the prominent eclipse chasers that year were Vassar astronomer Maria Mitchell and a young Thomas Edison. Author David Baron explores this history in his new book, American Eclipse. In his talk, he will share how he brought this forgotten tale to life.

Description:  The August 21, 2017 Total Solar Eclipse gives us an opportunity to study the Sun's cornea through imaging.  Mitzi Adams will discuss the Citizen CATE (Continental America Telescopic Eclipse) and the Megamovie projects which offers a unique opportunity for volunteers across the U.S. to get involved in research focusing on the cornea.

Exhibitor Stage (Indoors)

Curious to hear more from exhibitors about their plans for the eclipse or from vendors about the latest equipment and view/photograph the eclipse, Sun and night sky?  Our "Exhibitors Stage" will feature presentations by a variety of speakers to get you ready for the "big day".  The schedule of "Exhibitor Stage" speakers will not be available until the day of the expo. 

Workshops (Indoors)

For more in-depth programming on a variety of topics, two workshops are planned that will last 60 minutes each:

Description: The eclipse is coming and you plan to host a viewing Now What? Come and join in a discussion of things to consider, including viewing procedures, event tips, background information to share with your attendees, safety concerns, and activities to do while waiting.

  • 2:30 pm - 3:30 pm: "Eclipse Photography" - Mike Reynolds, Ph.D., Florida State College, Professor of Astronomy

Description: Since the first total solar eclipse photograph taken at the July 28, 1851 total solar eclipse by Julius Berkowski, astronomers and photographers have pointed their telescopes, lenses, and cameras toward the totally-eclipsed sun to try to capture the moment. Great images have become more likely, even for first time eclipse imagers, with the advent of DSLR cameras. What exposure should I take? What’s the best telescope to give me the sharpest image? What camera settings should I use? Explore the nuances of solar eclipse photography, from capturing the magnificent solar corona to the moon’s shadow and the sunrise-sunset effect.

Due to space limitations, only 100 attendees will be allowed to participate in each workshop session.  Please visit the "Information Center" to register for the workshop.
