Some residents of South Carolina received a terrifying awakening on February 13 morning when their sky flashed bright blue and a large object was seen plummeting from the sky.

The unidentified flying object caught around Greenville county exploded in a few brief seconds causing an alarming boom that shook homes in several cities. Over 30 emergency 911 calls were placed to at least one local police station while a number of fire fighters were dispatched before its mystery was solved.

"It sounds like a typical bolide," Charles St Lucas of the Roper Mountain Science Center told Fox4 of what he believes was a meteor, albeit early of their next expected shower in late April.

"This one broke apart into three or four different pieces, glowed a bright blue white," he said, calling its spontaneity "delightful."

With the sighting shortly before 2 am, most residents didn't take it as coolly.

"I thought the aliens were coming," one resident, Cindie Stubbs, told Fox4 with nervous excitement after witnessing the flash herself from above her home.

"I saw this bright light that made the sand sparkle."

Bolides, according to the American Meteor Society, are a special type of fireball or astoundingly bright meteor.

They are known for exploding before their landfall with a bright flash, similar to the blue one seen around Greenville.

St Lucas said that the blue coloring indicates that it was composed of copper.

Being naturally occurring elements, it most likely wasn't falling "space junk," he reasons. Injuries and damage from the sighting have not been reported.
