The 2017 American Solar Eclipse

2017 Solar Eclipse - Nashville is Centered to Deliver

On August 21 this year, a total solar eclipse will be visible in the United States. The last time a total solar eclipse was visible in continental North America was in 1979 in Canada. Nashville will be the biggest city along the viewing path of the 2017 Total Solar Eclipse. Bass, Berry & Sims is excited to celebrate this rare event from our headquarters in Nashville.

During the next month check out this webpage and the Bass, Berry & Sims Twitter feed (@BassBerrySims) for updates. Mark Manner, Bass, Berry & Sims attorney and respected amateur astronomer, answers key questions and provides important insights on what to expect during this significant occasion.

Why use solar viewing glasses?

Since it’s dangerous to look directly at the sun, use solar viewers leading up to and following the 2-minute total phase of the solar eclipse to filter out the sun’s damaging rays, including visible light, UV and infrared.

Since the surface of the sun will be totally obscured during the 2 minutes of the total eclipse phase, you must remove the glasses to view the delicate solar corona with the naked eye.

Do not use glasses if there are holes in the lens or with anything other than the naked eye. Specifically, do not use the glasses with binoculars, telescopes, spotting scopes or any other optical device.

Several retailers are selling solar glasses to enhance your viewing experience. A quick Google search will provide a list of online retailers.


Where is the total eclipse visible?

While most of the continental United States will be able to see a partial eclipse on August 21, an approximate 75-mile wide stretch from Oregon to South Carolina will be in the path of the total eclipse, including Nashville. If it is not cloudy, Nashville and the surrounding area will be able to witness this event for about 2 minutes (up to a bit over 2.5 minutes for those closer to the dead center of the eclipse path).

During the total eclipse, observers can expect the sky to darken to dusk level, the temperature to drop and the planets and stars to be visible to the naked eye. If the observer is positioned on a relatively high spot, a ring of daylight can be seen in the 75-mile diameter circle around them. The dark shadow of the moon can sometimes be seen approaching the observer from the west at over 1,000 miles per hour right before the total phase of the eclipse begins.

During a total solar eclipse, the moon is positioned exactly between the earth and the sun and, for a short period of time, totally obscures the view of the sun’s surface for observers along a specific pathway across the globe.

While a total solar eclipse happens every year or two somewhere on earth, in most cases, the eclipse is of very short duration, over water, or visible from a location that is remote or cloudy. Partial solar eclipses are much more common, but since part of the surface of the sun is still exposed, filters must be used throughout the event and the delicate beauty of the sun’s outer atmosphere isn’t visible.

He is listed as a co-author on several scientific papers reporting on the discovery of exoplanets, and has been fortunate to witness three previous total solar eclipses, in Canada (1979), Hawaii (1991) and Aruba (1998).

Mark has contributed content and research to several academic articles on astronomy, including the recent discovery of a new planet:
