Join us at Kennesaw State University (KSU) as the sun, moon and earth align on August 21, 2017!!!
The Department of Physics Professors will be there with solar telescopes, eclipse-related displays, presentations and to answer any questions you may have. What a great way for KSU Students to experience this once in a lifetime event!!!
Kennesaw State physics professors will be on hand during live viewings at two campus locations:
Kennesaw Campus – Campus Green between 1-3 p.m. with Kevin Stokes, chair of the Department of Physics, overseeing the viewing site;
Marietta Campus – By the globe in front of the Joe Mack Wilson Student Center, with David Joffe, associate professor of physics, from 1-3 p.m.
A limited supply of viewing glasses will be available at both live viewing locations.
A live-streamed viewing on the Owl View digital wall in Sturgis Library, first floor, will also available from 11:30 - 3:30 p.m.

Following the recommendations of American Astronomical Society (AAS) and National Aeronautics and Space Administration (NASA), the solar eclipse glasses that will be distributed at Kennesaw State University were purchased from authorized dealers of eclipse glasses: Thousand Oaks Optical and Lunt Solar Systems. These reputable brands have been verified by an accredited testing laboratory to meet the ISO 12312-2 international safety standards.

What is a solar eclipse?
A solar eclipse occurs when the moon, in its orbit around the earth, passes directly in front of the sun. It turns out that the apparent size of the moon is almost exactly the same as the apparent size of the sun in sky. The moon is tiny (in astronomical terms), but close to the earth, and the sun is enormous, but very far from the earth. Both appear about the same size as a penny held at arm’s length. When the moon passes directly in front of the sun, it can completely block the sun, except for the sun’s corona, (the sun’s outer atmosphere). This is a total eclipse. A partial eclipse is when only a portion of the sun is blocked.
Why is this such a big deal?
Solar eclipses are not that rare, maybe two every three years, but typically only a small part of the earth will be in the moon’s shadow and see a partial eclipse. Even a smaller portion of the earth will see a total eclipse. Of course, this may only be visible from the ocean or some remote location. On August 21, 2017, the path of the total eclipse will be all the way across the continental US. Although everyone won’t experience a total eclipse, everyone in the continental US will see at least part of the sun blocked by the moon. Look at NASA’s maps here: https://eclipse2017.nasa.gov/eclipse-maps
Why is it not safe to view a solar eclipse directly?
It not safe to look directly at the sun whether or not part of it is blocked by the moon. We just don’t normally have to remind people not to stare at the sun.
How can you view the eclipse safely? Photo of solar eclipse glasses
You can only directly look at the sun through special solar filters or solar eclipse glasses. These glasses only allow 1,000th of 1% of light to get through. That’s 1/100,000. Regular sunglasses will not work; they allow about ½ of the light through. Compare 0.5 (sunglasses) to 0.00001 (solar eclipse glasses). The sun will be the only thing visible when you look through the solar eclipse glasses, everything else will appear dark. A shade 14 weld lens is acceptable, too. The American Astronomical Society (AAS) has recommendations for where to get eclipse glasses from reputable sources ( https://eclipse.aas.org/eye-safety).
What will we see at Kennesaw State?
We will get to see a partial eclipse from both campuses. The first “contact” of the moon with the sun will be at 1:05 pm. This is when the moon just begins move in front of the sun. The maximum eclipse will be at 2:36 pm. The Kennesaw campus will see 97.6% of the sun blocked, and the Marietta campus will see 97.5% of the sun blocked. Remember, even the 2.5% of the sun’s light that is left is enough to damage your eyes. There is a good animation of what we will see at https://www.timeanddate.com/eclipse/in/@7318024
