Consider this your reward after a long work week: The heavens are set to go wild Friday with a full snow moon lunar eclipse and the closest brush Earth has had with a comet in three decades.

Friday's event is being referred to as a "Full Snow Moon Penumbral Eclipse," because of an old tradition in which each month's moon was named to describe the time of year.

The eclipse is expected to start around 5:34 p.m. EST, with East Coast residents having the best view. Paul Cox, an astronomer at Slooh, told NBC News that East Coast residents should be able to see the spectacle "an hour or so into the eclipse when the moon has risen."

"We will watch as the Full Snow Moon gradually fades from its left-hand side as it's bathed in the Earth's penumbral shadow. The effect is subtle and is easier to see in a series of images than with the naked eye — but it is possible to see with the naked eye," Cox said.

The greatest eclipse will occur at 7:44 p.m. EST, making it easier for East Coasters to get the best views halfway through the four hour and 19 minute long eclipse.

Even after the eclipse is over, it will still be a busy night in the sky. Comet 45P is set to have its closest brush with Earth Friday at 10:30 p.m. ET, marking the nearest encounter in three decades, according to Slooh.
