A typical location on Earth gets one total solar eclipse every 375 years on average. And Chou is anxious about first-timers and other folks who might look up at the spectacle without much forethought.
On Monday, August 21, the Pacific Northwest will catch a glimpse of a rare astronomical event: a total eclipse, caused when the moon moves directly between the sun and the earth.
This solar eclipse will be visible across all of North America.
For those that are traveling to OR and into the path of totality-that is, where the moon will completely block the sun-a partial eclipse will start around 9:06 a.m., peaking at around 10:15 a.m., when the earth will darken for around two minutes. Floyd County Schools (FCS) will delay school dismissal that day by approximately 30 minutes to help ensure the safe viewing of the eclipse and a safe dismissal of students.
Don't think it's safe to take quick, surreptitious glances, he warns. However you can still damage your eyes that way.
No photograph has ever captured the full drama and beauty of a totally eclipsed sun as seen with the naked eye. The ISO has developed its own event-day forecast using August 22, 2016 - also a Monday - as the basis for projecting expected demand the morning of the eclipse.
"We see the evidence of nanoflare heating, but we don't know where they occur", Caspi says.
In case you have been out of touch for the past several months, read this carefully.
The manufacturer name and address should also be printed on the glasses-be sure it's one of the five NASA recommends. So far, they've sold about 65 million.
Total solar eclipses offer unprecedented opportunities to study Earth under uncommon conditions. The ISO has also been working with gas pipeline companies, utilities and generators to procure additional reserve and regulation capacity, both of which will be needed to grapple with the potential for oversupply and frequency regulation issues after the eclipse, as solar rapidly ramps up its output.
"We're going to get about 96 to 97 of the solar disk covered", said Fisher.
The concern is that scammers appear to be selling bogus products. We humans have a natural reflex to look away from the sun, but the retina doesn't sense pain.
He explains that real solar viewers are thousands of times darker than regular sunglasses. Also look for a "CE" designation. When looking though the telescopes, you may be able to see the effect of the terrain on the moon on the solar shadow. A list of the distributors are on the Cheyenne Eye Clinic website.
If you'd like to see the total eclipse, you'll need to travel 37 miles southwest. If any other lights are visible, the filter is not safe to use.
NASA has a cheat sheet on taking images of the eclipse with a smartphone.
