In Portland, the fullest possible eclipse experience happened at exactly 2:45:53 p.m. Monday. That’s when about 58 percent of the sun was eclipsed by the moon, according to the U.S. Naval Observatory. Here, the moon obscures a small part of the sun.

The partial solar eclipse was visible in Monument Square in Portland, where many people turned out to view it. This is the view at 2:46 p.m. The photo was taken with a DSLR camera.
