The 2017 Total Solar Eclipse in Georgia and North Carolina
On 2017 August 21, a total eclipse of the Sun is visible from within a narrow corridor that traverses the United States of America. The path of the Moon's umbral shadow begins in northern Pacific and crosses the USA from west to east through parts of the following states: Oregon, Idaho, Montana, Nebraska, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia, and South Carolina (a tiny corner of Montana and Iowa are also in the path). A partial eclipse visible from a much larger region covering all of North America (See Map).
Knoxville, Chattanooga, and Atlanta are all near misses (eclipse magnitudes 0.997, 0.993 and 0.971) as the eclipse track crosses the Blue Ridge Mountains separating Tennessee from Georgia and North Carolina. However, only the northeast (Chattahoochee National Forest in Georgia) and southwest (Nantahala National Forest in North Carolina) corners of these two states lie within the path. The shadow quickly sweeps across them before entering South Carolina, the final state in the eclipse track.
Safe Eclipse Viewing
Every total eclipse of the Sun begins and ends with a partial eclipse. The partial phases require either a projection technique or a special solar filter to be viewed safely. Read more about this at Safe Solar Eclipse Viewing.
Of course during the few brief minutes of Totality when the Sun's disk is completely covered by the Moon, it is then safe to look directly at the Sun with the naked eye or through a telescope or binoculars.
Weather Prospects in Georgia, North Carolina and South Carolina
(Excerpts from Eclipse Bulletin: Total Solar Eclipse of 2017 August 21)
It is mid-afternoon when the shadow passes though Georgia, North Carolina and South Carolina. Convective cloud buildups will be increasing, replacing the more sedate cloudiness of the morning hours. Even so, the cooling that comes with the eclipse shadow should have a dramatic effect in dissipating the cloudiness provided the buildups haven’t reached the rain-producing stage.
Once over the Blue Ridge Mountains, the track passes over a landscape that is dropping sharply in elevation toward the Atlantic coast. Alas, it has little impact on the cloud cover, as this part of America is now supplied by moisture from the warm waters along the coast and moist air is available in abundance no matter which way the wind blows.
Average cloudiness does not decline on the east side of the Appalachians according to both satellite and surface observations, at least until the Atlantic coast is reached. Eclipse observations will be a challenge. Anderson, SC, has an observed cloudiness of only 50% on average, but the calculation is affected by a strange absence of "scattered" cloud reports and a high frequency in the "few" category in the official record. In all likelihood, the value there will be similar to those elsewhere in the state.
The best observing site in the Carolinas is likely to be right on the coast. Since convective clouds build from the heating of the land, ocean side viewpoints are able to take advantage of lower cloud levels in the cooler air that flows inland from the offshore waters. A site could be selected in Charleston, though the city is well off the central line and the time penalty would be significant. Better is a seaside park such as Buck Hall Recreation Area, about 2 1/2 miles from the central line. Buck Hall is a small park however and cannot accommodate a large crowd. Access to the waterfront is limited by marshy offshore islands and private homes along the coast, but it should be sufficient to be within a mile or two of the Atlantic to take advantage of the cloud-suppressing winds from the east.
South Carolina is no stranger to Atlantic hurricanes and so the possibility of one of these storms in the days surrounding the eclipse, though very small, cannot be discounted. Storm statistics for the Carolina coast reveal that the eclipse comes at a time when the frequency of tropical storms is on the rise toward its mid-September peak. Since 1867, 43 hurricanes have made landfall over South Carolina. Of these, 5 occurred within the four-week period centered on the date of the eclipse. Talk about hurricanes with any long-term South Carolina resident and the names Hugo (1989), Charley (2004), and perhaps Gracie (1959) and Hazel (1954) will come quickly into the conversation. Of these, Hugo, at category 5, was the strongest, bringing wind speeds of 140 mph when it made landfall right over the eclipse track on September 22.

Eclipse Circumstances for Cities in Georgia
The table below lists eclipse circumstances for a number of cities in Georgia. The following information is given for each city.
- The type of eclipse seen from the city (Partial or Total).
- The times when the partial eclipse begins and ends.
- The times when the total eclipse begins and ends.
- The time of maximum eclipse.
- The altitude on the Sun above the horizon (in degrees) at each of these times.
- The Eclipse Magnitude at maximum eclipse. Eclipse Magnitude is the fraction of the Sun’s diameter occulted by the Moon.
- The Eclipse Obscuration at maximum eclipse. Eclipse obscuration is the fraction of the Sun’s area occulted by the Moon.
- The Duration Total Eclipse is the length of the total phase in minutes and seconds (i.e., totality).
Thanks to Bill Kramer (Eclipse-Chasers.com) for helping to develop the code to generate the above eclipse circumstances table. To calculate predictions for other cities see 2017 Eclipse Circumstances Calculator.
The partial phases require either a projection technique or a special solar filter to be viewed safely. On the other hand it is completely safe to watch Totality with the naked eye. For more information see Safe Solar Eclipse Viewing.
Animation of the Moon's Shadow Across Georgia
The animation above shows the Moon's umbral shadow as it tracks across Georgia. Observers must be inside this path to see the total eclipse. Outside the path only a partial eclipse is seen.
