What is a solar eclipse?A solar eclipse occurs when the moon passes between Earth and the sun, blocking at least part of the sun as viewed from some areas of the earth. During a total solar eclipse, the moon completely obscures the sun so that only the sun's corona is visible for a moment in time. On August 21, 2017, a total solar eclipse will be visible along a roughly
67-mile wide path across the United States from Oregon to South Carolina.

Where can I see the eclipse at Manhattan Project NHP?The entire area of the Oak Ridge Unit will fall under the path of totality for the eclipse, providing opportunities for viewing, weather permitting. The following are approximate durations for totality and locations in or near the park.
The park is currently planning organized public viewing events at:
The partial phases of the eclipse will begin at approximately 1 p.m. ET and end at approximately 4 p.m. ET. The total phase of the eclipse will occur at approximately 2:30 p.m. ET, with the duration of totality varying depending on the specific viewing location.
SafetySpecial viewing glasses are required in order to safely view the solar eclipse, and are available for purchase at AMSE, if needed. It is best to purchase them before you enter the park to ensure you have them for viewing. You may (and should) take them off only during the totality (less than two minutes) or you will miss the highlight of the eclipse!
Planning for the eclipseAugust is typically a busy time of year in the park. The solar eclipse will bring even more visitors to the area, so expect traffic delays and congested parking lots. Please note that eclipse viewers may need to make special plans to avoid viewing the astronomical event while caught in traffic. Contact the visitor center for alerts and current information.
There will be no charge to participate. Vehicle access to these sites, though, may be closed when parking becomes full or roads become congested.
Visitors may also view the eclipse from other areas of the park on their own, such as:
