All around the office we are all hearing about the excitement of the upcoming eclipse on August 21st, 2017. Everyday we've been answering questions regarding its arrival, what to expect and most importantly how to make sure our eyes are well protected.
As you probably already know, the Chattanooga area will be experiencing the first solar eclipse since 1865! Even though Chattanooga is only experiencing a partial eclipse, we will still receive 99.5% of the total eclipse.
The moon will cover at least part of the sun for 2 to 3 hours. Halfway through, anyone within a narrow path from Oregon to South Carolina will experience a brief total eclipse. The moon will completely block the sun's bright face for up to 2 minutes and 40 seconds. Day will turn into night, and (weather permitting) one of nature's most awesome sights will become visible: the sun's shimmering outer atmosphere, or corona.
11 Things That Everyone Needs to Know
• Partial Eclipse will begin at 1:02pm
• Peak Eclipse will be at 2:32pm
• The event will finish at 3:58pm, lasting a total of 2hrs and 56mins
•The total phase of this solar eclipse is not visible in Chattanooga
• Because we are not receiving a total eclipse in our Chattanooga area ECLIPSE GLASSES MUST BE WORN DURING THE ENTIRE EVENT.
• Use approved solar eclipse viewers. The only safe way to view a partially eclipsed sun is through special-purpose solar filters, such as "eclipse glasses" or viewers that meet international standard ISO 12312-2 for safe viewing. Sunglasses, smoked glass, unfiltered telescopes or magnifiers, and polarizing filters are unsafe. If you can't find eclipse viewers, build a pinhole projector to watch the eclipse.
• Technique of the pros. Before looking at the sun, cover your eyes with the eclipse viewers while standing still. Glance at the sun, turn away and then remove your filter. Do not remove the filter while looking at the sun.
•Totality awesome. I highly recommend that, if possible, travel north to the area within totality ( see map ) to experience the full eclipse. By doing so you will be able to remove your protective eyewear during the total eclipse. During this awesome moment you'll be able to observe the corona of the sun surrounding the moon. Unfortunately in the Chattanooga area you won't be able to see this corona surrounding the moon because the solar viewers are extremely dark and will obscure this view.
• The last total eclipses visible in the Chattanooga area was on July 7, 1442, and July 29, 1478, (right at sunrise) with annular eclipses Dec. 25, 1628, (right at sunrise) and Oct. 19, 1865.
• The next total eclipse Chattanooga can anticipate seeing is on Aug. 16, 2566, with 2 minutes and 15 seconds of totality.
• And of course if you should experience discomfort or vision problems following the eclipse, please call the office. The sun's damaging rays can cause a very serious condition called solar retinopathy which can result in partial or even permanent vision loss.
Thank you and we hope everyone enjoys this once in a lifetime experience.
