UW Professor Heads State Portion of NASA Project to View August 2017 Eclipse

(Fremont County, Wyo.) - The next total solar eclipse to cross the United States is scheduled to occur Aug. 21, 2017 and the University of Wyoming will help provide a bird’s-eye view and front-row seat to this historic phenomenon. “It’s a spectacular thing to see. It’s predictable, but it’s a once-in-a-lifetime opportunity,” said Michael Pierce, a UW associate professor in the Department of Physics and Astronomy. “It’s awe-inspiring. You see a part of the sun that is never seen. This will be something that people will tell their grandchildren about.” Pierce is the Wyoming state coordinator for NASA’s Citizen CATE (Continental-America Telescopic Eclipse) Experiment. Using 61 telescope stations across the country, including nine in Wyoming spaced approximately 50 miles apart, the project’s goal is to create a continuous 90-minute movie of the solar corona during the total eclipse. Researchers and scientists hope to gain a better understanding of the sun’s inner corona. A total solar eclipse is when the moon’s shadow touches the Earth and blankets portions of it in total darkness for a few moments. In essence, the sun, moon and Earth align. A person in the dark part of that shadow, known as the umbra, will see a total eclipse. A person in the light part, called the penumbra, will see a partial eclipse. Pierce says scientists want to study the behavior of the hot gases in the sun’s inner solar corona. “The temperature changes dramatically, from 6,000 degrees at the surface of the sun. Then, the glow (resembles a diamond) you see around the sun during the eclipse goes to 1 million degrees,” Pierce explains. “This is a rapid temperature change. The inner part of the corona has complex filaments that look like fingers, and these trace the sun’s magnetic field.” New scientific results about the dynamics of the magnetic fields and plasmas in this part of the solar corona will be derived from the data collected at the 61 telescope sites nationwide.

High school science teachers and students will man the telescopes and, using a laptop hooked to each, video record the total eclipse at each point, Pierce says. “The inner part of the corona can only be seen during a solar eclipse. We’ll end up with a nice video that shows how the corona changes in time,” Pierce says. “In 1979, the last total eclipse in the United States, we did not have these technological capabilities. Before the Internet and digital cameras, we had a few pictures here and there. This is the first time we can do this experiment.” The last total solar eclipse to cross the continental United States occurred Feb. 26, 1979 -- more than 37 years ago. This next one will start in Oregon and move in a southeasterly direction all the way to South Carolina, Pierce says. The southern part of Grand Teton National Park will be one of the best places in the entire country to view the eclipse, according to the website Eclipse2017.org. On the centerline, Pavillion (at 11:38), and Shoshoni and Riverton (at 11:39) will experience 2:23 of the great show, before landing squarely on the city of Casper. “When the eclipse is over, all of the schools participating will get to keep the telescopes and video cameras,” Pierce says. “The hope is the 60 groups across the country will be kind of networked together with contact information and be well-trained in the use of the telescopes. People in the project are currently planning educational activities after the eclipse aimed at sustaining student interest in astronomy.” Feature Photo: Photo via Shutterstock / Pitchengine Communities #county10 #news
