So this one is a bit of a stretch, but the eclipse DOES happen on a Monday, and a full moon is known to make people a little insane. That's the least of the ocular problems that can occur.

"It's really important to resist the urge to look even momentarily, directly in the sun because you have no real sense of time", says Dr. Christopher Quinn, president of the American Optometric Association. And those changes start as chemical changes in the photoreceptors, the rods and cones in your eye. It happens to be where a lot of the most interesting solar physics happens. A number 14 welding filter would be adequate also. Viewing glasses will be availabe while supplies last, as well a materials to make a pin hole viewer. "For 20 years it's been one of my bucket list items; if something doesn't work, I have seven more years to the next one, right?" But they should have a stamp on there that says they are ISO approved for viewing the eclipse. "We'll come around one more time and from the station side we'll see about an 85 percent eclipse of the sun looking up (at 4:17 p.m.)". Pinhole viewers create a reflection of the eclipse by filtering the light through a small opening.

"I was sitting on a beach with my back to the jungle, and if you know anything about jungles, they are not usually quiet", she said.

"They'll certainly react to the dark and temperature and react to environment, but to see whether they react to it in a meaningful way is hard to tell", said Steve Ross, director at Lincoln Park Zoo's Fisher Center for the Study and Conservation of Apes. Using a tripod can help you stabilize the camera and avoid taking blurry images during the low lighting.

That's a great question. So for those cities - and anywhere else with a partial eclipse - you need to keep those solar specs on the whole time.

Get in touch with us on Twitter and Facebook . "[They have made] good additions to the quality they already have there". Mustafi, along with Rob Holding and Nacho Monreal, will play in the three-man defence. "He is focused.

NASA is looking for citizen scientists, to take temperature measurements during the eclipse, to see how the Moon's shadow (even away from the path of totality) affects temperature and weather here on Earth.

That they accidentally viewed that?
An eye care specialist will be able to determine the level of damage upon examination, he said. "If you don't do that soon, it's going to be too late". That's the bad thing.

Considering that demand, the American Astronomical Society has updated its safety advice "in response to alarming reports" of unsafe eclipse-viewers popping up online.

The Dow Jones industrial average fell 0.93 percent, with the tech-heavy Nasdaq composite index declining 2.13 percent. Silver added 0.4% to $17.15 USA per ounce after hitting $17.24, its highest since June 14, in the previous session.

"This is historical, and I would encourage everyone to see it", said Nathan Podoll, M.D., assistant professor of Ophthalmology and Visual Sciences at Vanderbilt University Medical Center (VUMC). That will cause a reduction in vision. The damage can be temporary or permanent. "It doesn't take very long before you're exposing your eyes to serious risk".
