A partial solar eclipse occurs when the moon passes between Earth and the sun but only partially covers the sun's disk. Unlike in a total solar eclipse, the moon didn't completely block out the sun this time, so observers needed equipment such as eclipse glasses or pinhole cameras to view the sun safely.

Parts of the northeastern U.S. and Europe witnessed a partial solar eclipse on Saturday. Here's some photos of what they saw.

Unlike a total solar eclipse, part of the sun is still visible during a partial solar eclipse, so there is no darkening of the sky or visible solar corona.
