Viewing Safely

    Use Eclipse Glasses or Grade 14 Welder's glass or reasonably priced Polymer Filter from vendors such as Thousand Oaks Optical (click on the picture below for more details about viewing safety).

    Do Not Look at the Sun Directly.

    During the few minutes of totality, the visible corona is about as bright as the Moon, so it is safe to view directly. During the much longer partial eclipse times (including the Diamond Ring and Bailey's Beads phases), it is dangerous to view the Sun directly (you must use a dark filter).

Total Eclipse in Rabun County/
Partial in Atlanta (Viewing Arrangements)

Most of North America will experience an eclipse of the Sun on Monday, August 21, 2017. The best views will occur along a narrow band where the Moon will totally block the Sun for over two minutes. This shadow band will cut through the north-east part of Georgia. The Georgia State University Department of Physics and Astronomy is participating an eclipse viewing event there in collaboration with the Rabun County Tourism Development Authority and Rabun Gap-Nacoochee School (click for details).

--- If you cannot travel to the path of the total eclipse, consider joining a GSU on-campus observing group who will host an observing session between 12PM and 3PM on August 21 in front of 25 Park Place and in conference room #223 in 25 Park Place. The Sun will appear 97% blocked from Atlanta, but the glare from the 3% remaining sunlight renders the corona invisible. An interactive map of the Eclipse path with details such as duration and start and end times are given here---

Some More Information...

  • This is the 145th Saros Series. More information on the Saros cycle is here
  • The longest duration of the eclipse is 2m40.2s and will occur at the latitude 37 deg 35'N & longitude 89 deg 07'W.
  • At the Rabun Gap-Nacoochee School, the eclipse will begin (first point of contact) at 1:06 pm. Totality begins (second point of contact) at 2:35:40 pm and ends (third point of contact) at 2:38:18 pm. The Diamond Rings can be observed around the second and third points of contacts, while the corona is only visible during totality. The eclipse ends (fourth point of contact) at 4:01 pm.
  • Beautiful structures in the corona, called streamers, often exaggerated in photographs will not be visible because the Sun is currently in the Solar Minimum Phase.
  • ** Whether the Sun is in Solar minimum or maximum, streamers are an optical illusion.**

Interesting Observables during an eclipse

  • Drop in the ambient temperature. Measure using a thermometer. Use the GLOBE Observer app to report your temperature. If you are in the partial eclipse path, report anyway to compare.
  • Birds start flying toward their nests. They are easily confused.
  • Observe which constellation of stars the Sun appears in, and compare that with the zodiac constellation associated with the date (August 21) used by "horoscope" calendars.
  • Planets Mercury, Venus, Mars and Jupiter are visible in the sky near the Sun once it starts getting dark.
