IMG_20170821_124059 Watching partial solar eclipse
Ray and R are watching partial solar eclipse at the eclipse watching "party" in the Balcones Park. In Austin, Texas the maximum coverage of the Sun was 65%, and it didn't make any noticeable difference in the brightness of the Sun. Any wispy cloud passing over the Sun dimmed it more than the Moon passing over it. August 2017.
