Eclipse. "Red is grey and yellow white..."

[Dave from Dayton 3,077]

The dimness should become more noticeable about 15 minutes before the eclipse reaches totality. To many people, the light takes on a metallic or silvery quality.

There is more to this event than the moon blocking the sun in the sky.

Are you ready for The Purkinje Effect? Red and green colors will look strange when the light dims. That is because our eyes and brain adjust to and interpret that change.

"As light dims, our eyes transition from photopic vision, associated with the retina's cone cells that deliver full colors and fine detail, toward scotopic night vision that relies on rod cells to detect objects in low light. In the middle is mesopic vision, the transitional phase where both rods and cones are active.

When the light's intensity dims in the eclipse, colors with longer wavelengths, like red, will look darker as cones become less active. But because rods are sensitive to the shorter blue-green wavelengths, those colors will have a chance to shine."

The dimness should become more noticeable about 15 minutes before the eclipse reaches totality. To many people, the light takes on a metallic or silvery quality.

Some shadows will sharpen; others will alter.

For one thing, your own shadow will be different.

"The change in lighting makes shadows look sharper on the ground, so it's possible to see individual hairs on your head in your shadow," according to the European Space Agency."

"And if you see the sun's light coming through tight gaps in trees, you might notice lots of little crescents. As the ESA says, "The tiny gaps in the leaves will act like multiple pinhole cameras, projecting the Sun's image to the ground."

People in the eclipse's path can also see an odd shimmering called shadow bands.

"A minute or two before totality, ripples of light may flow across the ground and walls as Earth's turbulent atmosphere refracts the last rays of sunlight," as the EarthSky website said in 2017.

Other changes to expect include a drop in temperature — and the appearance of colors in the sky that will make it seem as if you're seeing a sunset (or sunrise) across the full 360 degrees of the horizon."

Working from home tomorrow- they’re anticipating an 11 hour standstill in Brown County. No way that I’m dealing with that ish

The lunatic is in my head
The lunatic is in your head
You raise the ball
You make the call

You rearrange it 'til you're sane
You lock the door
And throw away the key
There's someone in your head, and it's Woody

And if the cloud bursts thunder in your ear
You shout and no one seems to hear
And if the band you're in starts playing different tunes
I'll see you on the dark side of the moon

 

I can't think of anything to say except, laughing is nice
