The stiff breeze is the only thing that is keeping the heat and humidity from feeling oppressive. It would be a good night to go out to observe the Moon if it weren’t for the wind buffeting the telescope.

When I got out of the library I could see the Moon hanging above the buildings down the hill on Fordham Rd so took a qhick look with the compact binocular. The wind was pushing me around but it looked like the terminator was outside of Mare Imbrium.
