We had the corner of an 80% eclipse in Seattle, maybe five years ago?
Almost cloudless summer sky.
A TOTAL disappointment.
The air briefly cooled off, but the sunlight barely dimmed.
No stars visible. No night birds chirping.
Like a completely average cloudy day in the winter time.
Even in a 95% eclipse, you will not notice too much change in the brightness of the day. That is because the sun is so bright that even a small portion of it is still enough to light up the sky. You actually need to get to about 99% totality before it actually starts looking like night.
