@Laura- very cool that it’s a sine curve! I want to be in the far north for the summer solstice some time – far enough for 24 hour daylight. I’ve been places where it’s light at 3 a.m., but not all the way.

In terms of light, I read a blog post by Diane (Life Off Headset: https://lifeoffheadset.com/) yesterday. It’s worth a read!
Here is a snippet:
“I know the way the light falls is just how the earth spins and tilts, but it seems like there is some cosmic plan here. Why else would the world look so beautiful just when I don’t feel like I have the time to slow down and not miss it? I mean now, when it is so cold outside and the dirty slush soaks through my poor choice of footwear? When all I want to do is be back inside my house, something is telling me that, “No, actually, what you need is fresh air. There is plenty out here if only you will pause and look and breathe.”

Of course I know that in a few weeks, the sun will hit that special horizon spot at a different point in my day. It will be there slanting through the kitchen window as I make breakfast, lunch and prep dinner. Morning activities that once felt practically nocturnal when carried out in the pre-dawn darkness will now feel very much part of the day.

I guess the sunlight will always peek through the trees and over rooftops twice a day. The rays will come through the kitchen window in the morning and flood the living room in the afternoon. It’s a predictable yet moving moment.”
