Yesteday at 12:22, the sun was overhead, perfectly overhead. It only happens in the tropics. Above is a picture of a hole where there was a pipe fence post. You can’t tell from the photo, but it’s about a foot deep. The black is the insides of the pipe, not a shadow. The sun is shining all the way to the bottom. You can see the shadow from my phone, I was standing normally when I took the pic. The hole really is quite deep.
It would be cooler if the photo was better, 3D or stereo or something. But still, it’s an astronomical event I look forward to twice each year.
June 21st, the sun will be overhead at the Tropic Of Cancer, then it heads back south.
