What's with the ISS? Did the astronauts steering it break into the vodka reserves? No, the waviness of its path crossing the Sun was due to the air shimmering in the desert August heat at 102° F and the constant strong outflow winds from surrounding thunderstorms buffeting the scope broadside. Time = 6:24:40 pm MDT, Sun's altitude = 24°, ISS crossing time = 1.43 seconds.

I could have set up on the center line itself less than a mile away near an industrial area, but this place had shade trees.
