The top part of the moon will show the brightest color, as it will only miss the Earth's full shadow by about 100 miles.
But during a penumbral eclipse, like the one tonight, sunlight from the earth is only blocked by the outer shadow of the earth.
Comet 45P/Honda-Mrkos-Pajdušáková, named for the astronomers who discovered it in 1948, will make its closest approach to Earth since 2011, according to the Weather Channel.
You should look out for the comet from midnight on Friday because the comet make its closest approach to Earth on February 11.
That's because forecasts show almost 100 percent of the sky will be covered in clouds - snow clouds in many locations, which will impede viewing of the snow moon, according to National Weather Service forecasts. It's different from a partial or total lunar eclipse in that the moon will only be covered by part of Earth's shadow. Those on the look out could also see a penumbral lunar eclipse and a new year comet. (If you can't find Hercules you wouldn't have seen the comet anyway.) You will need dark skies-no light pollution-and binoculars or a telescope to see Comet 45P.
That is the name given to February's full moon.
The penumbral lunar eclipse is expected to happen around 7:43 p.m. Friday evening.
The comet will actually reach its nearest point to Earth on Sunday, then head back out into space before swinging back this way in another five years. Eastern Time. However, the greenish comet will be visible only by binoculars and telescope. The eclipse will officially end at 8:53 p.m.as the moon continues to rise.
