While not the most spectacular lunar eclipse, the moon still put on a show for astronomy fans on Friday evening.
A lunar eclipse occurs when the moon passes through the Earth's shadow. Depending on what part of the shadow the moon passes through will determine how vivid the lunar eclipse is.
"Shadows have three parts--the umbra, penumbra and antumbra, which are used to describe the relation of the shadow to the degree of light casting it," reported AccuWeather.com Staff Writer Samantha-Rae Tuthill.
"The umbra is where the shadow is deepest, as the light source is fully blocked by the object casting the shadow. The penumbra and antumbra occur on the edges of the umbra where some of the light source lessens the shadow," Tuthill continued.
"The light cast on the moon during a penumbral eclipse obscures the view of the shadow cast, making the eclipse hard to notice."
Friday evening's eclipse was a penumbral one, but some astronomy fans were still able to view and capture the slight dimming of the moon.

An unusually strong push of cool air for early September will move southward along the Atlantic Seaboard into the Labor Day weekend, before July-like heat returns by next week.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Nino.
After heat has dominated headlines this summer, cool air has finally taken control of the northern half of Europe with no signs of departing anytime soon.
Steering winds could take Ignacio, as a remnant storm, into the southeastern arm of Alaska or British Columbia during the middle days of next week.
While Tropical Storm Kevin will stay well away from Mexico, its moisture will still lead to an increase in showers and thunderstorms from Baja California to the Four Corners region of the United States.
A stormy weather pattern will prevail through September across much of southern South America.
