We first noticed a change around 11:55. Maximum seemed to be at 1:20 at our house. The sky did turn a darker blue and you could stand in the sun without broiling. Father noticed the temperature actually dropped a degree. I made sure to photograph the neat patterns made by the sun shining through the tree in the front. (The photos were taken of images from both our box viewers and a simple projection onto the ground. Here’s the post about the box viewers.)
