From upper left to lower right: 5:37:40, 5:38:20, 5:39:40 and 5:39:53 UT

Venus exit and sunlight scattering in its atmosphere (contrasts slightly exagerated: the arcs were fainter than sun's surface, and/or at least very thin (1-2" maxi)). Zenith is down, and South is up slightly to the left, East to the right.
