2017 Neff Public Lecture
Dr. Fred Espenak
Scientist Emeritus, NASA's Goddard Space Flight Center
On August 21, 2017, a total eclipse of the Sun will be visible from the contiguous United States for the first time since 1979. The track of the Moon's shadow cuts diagonally across the nation from Oregon to northeast Kansas to South Carolina. Inside the 68-mile-wide path of totality, the Moon will completely cover the Sun as the landscape is plunged into an eerie twilight, and the Sun's glorious corona is revealed for over 2 minutes.www.EclipseWise.com), eclipse photography (www.MrEclipse.com) and astrophotography (www.AstroPixels.com). Over the past 45 years he has witnessed 26 total eclipses of the Sun. In 2003, the International Astronomical Union honored Espenak by naming asteroid 14120 after him. Espenak now lives in Portal, Arizona where he operates Bifrost Astronomical Observatory.
