After a night of observation, I usually long for sleep. This desire is strongest between 3am and 5am. But it can also be a good thing if one doesn’t give in to this wish straight away, because a sunrise like that can also be great. In this case it was a birthday call that I still wanted to make before sleep and so I didn’t go straight to bed.
The sun is slightly deformed due to the earth’s atmosphere. The air acts like a lens and the path of light through the air is longest directly above the horizon. And actually the sun hasn’t even risen in the photo, the atmosphere allows that we can look around the corner. Without an atmosphere, the sun would only become visible in a few minutes.
Now it was really time for bed, so that I get 8 more hours of sleep together.
