Venus exhibiting the so-called “black-drop” effect at second contact, when the planet’s silhouette was first fully within the sun’s disk. This took place at 3:24 p.m. local time on June 5, 2012, with the sun 55 degrees high in the sky. The viewing conditions were not steady that day in Hermosa Beach, Calif., with atmospheric turbulence affecting the quality of the images.
