And another happy perihelion!
Also happy to see that the sun will finally start to rise earlier each day starting in a day or 2.

Happy Eclipse!

Safe & fun viewing, everybody! (For those of you in the eclipse zone today.)
I've got my welder's goggles sitting beside me. We're only expecting 60-70% coverage here in Eastern Ontario. Next total eclipse for us will be in 2024.
I've never seen a total eclipse. They're pretty amazing, from everything I've read.
I've got my

Crap. My welding glass is only #10 (I took it out of the hood to be sure).
According to NASA, #14 or higher is required.
And in a quick glance through #10, it does feel uncomfortably bright. One YouTube video suggests if you can see outlines of trees & buildings silhouetted against the daylit sky, they're not dark enough. You definitely can with #10.
Another option is pull the other #10 from my small welding mask and layer them. With effectively #20, the disc of the sun is dimly visible.

My auto-darkening helmet goes up to 13...but I have it on about half, and am wearing sunglasses behind it. Its about as dark, and I have that second layer of UV protection.

I tried my auto-darkening helmet too, but it kept flickering on & off. So I was getting blasts of full sunlight right into the old eye holes. No good!
PS: "fingernail" of the moon just became visible here about 10 mins ago.

Cloudless total eclipse here, great coronal show. Chickens, buzzards, and grackles went to roost at totality. The grackles took awhile to get their act together afterwards and fly away.

Lucky you!!
We had 60-70% coverage here. Cloudless sky!
The quality of the light changed in a weird way, the wind seemed to die down, the birds got quieter.
My #20 two-layer welding lenses worked fine.
For a relative with poor vision, I made a pinhole projection onto a piece of paper she held close to her face, just out of shadow (back to the sun), and she could make out the crescent of the sun.
It was fun to see crescent-shaped sun dappling on the ground in the shadows of some trees.

Sunshine = energy, which 'drives' wind motion; and that's why winds tend to die down at night time.

Yeah, you'd think as an avid sailor I would know that...
But I would have guessed there was more large-scale thermal inertia that would have kept the breeze going than blocking ~60% of the sun for a little while would have caused.
Learned something new today.
Anyway, we get a total eclipse here in eastern Canada in just under 7 years. I'm looking forward to it! I've never experienced a total one.
