A lunar eclipse occurs when the Earth is positioned directly in between the sun and the moon.
The phenomenon, which began at 17:00 GMT in the United Kingdom and ended at around 21:00, saw the moon move into Earth's penumbra, or outer shadow, causing it to look darker than normal.
According to the Old Farmer's Almanac, legend has it that wolves hungry from winter starvation howled more at the first full moon of the year than any other.
But those expecting the moon to turn red, a phenomenon dubbed the blood moon, were disappointed.
Ed Bloomer, an astronomer at the Royal Observatory Greenwich, said people in the United Kingdom would be able to see the display "nice and clearly".
The name "wolf moon", coined by Europeans and Native Americans, comes from the howling of wolves that could be heard in the depths of winter.

The first full moon of 2020 will arrive in style on Friday evening. The moon was noticed throughout the nation, from rural areas to London.
Earlier on Friday, Andrew Peters captured breathtaking scenes of the total moon setting over a historical ridge within the picturesque Shropshire Hills.
According to the Farmer's Almanac, Friday also marks the first "Wolf Moon" of the decade.
While January's full moon is named after the wolf, full moon in other months also have names to do with natural phenomena occurring at that time of year.
