NASA warns: Keep a wary eye on those glasses

10 August 2017

It should be noted that, while everyone can take a photo of the eclipse with any camera, some photos will turn out more detailed and clear than others depending on the kind of camera being used.

While past observations have been great for allowing us to understand what we now know, there's still a lot of information left to be gained by studying eclipses. That can easily be interpreted as, "this event is risky and should not be watched".

Another concern is that people may want to take photos of the eclipse while they're driving, which officials warn would be extremely risky. I explained to school staff we were going on an excursion. The Aug. 21 eclipse will be a huge draw for potential visitors, but there's a lot more to see and do in Redmond than just look (indirectly) at disappearing sun.

According to the American Academy of Ophthalmology, solar retinopathy is a photochemical toxicity and injury to retinal tissues. And it's a great teaching moment for our kids.

Las Vegas eye surgeon and Center For Sight medical director, Eva Liang, MD, cautions especially against allowing children to view the solar eclipse, without carefully selected eye protection and knowledgeable adult supervision.

This one will be different than the eclipse that occurred in Georgia in 1984. But the USA mainland hasn't seen a total solar eclipse since 1979, when it swooped across Oregon, Washington state, Idaho, Montana and North Dakota, then into Canada.

We can't stare at the sun without protective eyewear, though.

Kenya on a knife edge ahead of high-stakes elections
Incumbent president Uhuru Kenyatta , son of Kenya's first president Jomo Kenyatta, is in a neck-and-neck race with Mr Odinga. The last election in 2007 was marred with violence with more than 1,100 deaths and 600,000 others were displaced.

Amir Caspi of the Southwest Research Institute in Boulder, Colorado, and his team will use two of NASA's WB-57F research jets to chase the darkness across America on August 21.

The American Academy of Ophthalmology and the American Academy of Optometry are teaming up to offer tips on how to safely photograph an eclipse. "Some people are giving them out for free, or you can buy them for a dollar or two". Alternatively, micro explosions, termed nanoflares - too small and frequent to detect individually, but with a large collective effect - might release heat into the corona. "From what I've read, it's sometimes not until the next morning that people come up with eclipse blindness from where they've damaged their retina from looking at the sun", Walter said. In other parts of the country, the sun will be partially eclipsed by the moon. Scientists at the Griffith Observatory in California say they still get calls about this.

During the eclipse, keep the glasses on while you want to look at the sun.

Observations of Mercury will also be taken a half-hour before and after totality, when the sky is still relatively dark. Cut your glasses in half and tape one eyepiece over your smartphone camera lens.

When you put them on, "you shouldn't be able to see anything...except the sun itself", the organizations says. So, the last total eclipse seen on the east coast AND west coast was almost 100 years ago. Zoom out to see the path for the entire nation, or search for your address by entering it at the magnifying glass on the lower left.

If you'd like to enjoy the eclipse at the library, chairs will be set up outside and complimentary coffee will be available. Animals may become very quiet - or perhaps your neighborhood dogs will start barking! "We also lost a special sponsor due to money being tight, increases in advertising costs, needing to rent police because we are Irish and want Guiness, increased liability insurance, outhouses and trash removal are expensive.the same issues with any event".
