Everett, Washington, US -- Another night, another fireball.

The Snohomish County Sheriff's Office received a 911 call of streaking light in the night sky around 10:15 p.m. Thursday. It was similar to reports on Halloween night from people seeing a strange light in north Snohomish and Skagit counties.

One caller on Halloween described a large explosion of white light and thought it might have been a plane crash off I-5.

Shari Ireton, the sheriff's office spokeswoman, did some investigating Friday morning. She talked to a NASA scientist who believes he has an explanation: Taurid meteors.

He referred her to a NASA web page that offers a description of why the fireballs often can be seen each fall.

Initial Sighting Reports

15 November 2012 - Edsel. London, Ontario 06:40 EST

5 seconds duration - Traveling north west. It looked greenish in color. As bright as a full moon. I could see a tail with debris as it flared out in the sky.

15 November 2012 - Kevin. Monumental, West Virginia 06:40 EST

3 seconds duration - SE to NW direction. I was facing West. White/green color, no sound. Bright enough to be seen during daylight. Yes, I saw sparks.

15 November 2012 - Brian. Dayton, Ohio, USA 06:42 EST

5 seconds duration - Northeast to west. I was facing Northeast. White color at first, then green - no sound. Venus brightness. Trail of sparks visible. It looked like a star at first but I noticed it was moving very fast and then before I knew it, it was almost right above me and faded out as sparks streamed off the back and the flame turned green.

There was an unexpected sight in the sky Thursday morning for some 680News listeners, who called the newsroom to say they believe they saw an asteroid of meteor shooting over the sky around 6:45 a.m.

One listener named Sherry said she was waiting for a coffee when she saw a very bright light that caught her eye.

"You know how the North Star is really bright and big. From where I was looking it was five times bigger than that from the naked eye; it was huge, it was massive," Sherry said.

Although it's not yet confirmed, an astrophysicist and lecturer with the University of Toronto isn't doubting what people saw, and he too, is pretty sure it was a meteor.

"The 680News report that I got from a woman that I heard this morning, that sounded like there be some real meat to it," Dr. Ian Shelton said.

Initial Sighting Reports

08 November 2012 - April Medley, Clovis, New Mexico, USA 23:00 Mountain Time

20 seconds duration - Started above my house, went from South to North, I was facing North. White flash then saw a large falling "fireball" which had many large and visible fragments, latent visual trail was visible for about 20 seconds. Very unusual and large, seemed close. 5 minutes later I heard a large "boom" in the direction the body traveled. White light like other stars but brighter than all others I could see.

Some Calgarians with their eye on the sky early Monday morning may have witnessed a brief but bright meteor.

It happened around 5:30 a.m. on November 5th, and was captured on camera by Don Hladiuk, an astronomer at the Calgary Science Centre.

Traffic on Deerfoot Trail even slowed to view the rare sight.

Meteor hunters say they have found two more remnants of the streaking fireball that lit up California skies last month.

The latest find - reported on Thursday - was also in the San Francisco Bay area city of Novato and brings the total number of chunks of rock that fell from the Oct. 17 meteor explosion to four. The meteorites are known as metal chondrites because they contain microscopic metal particles called chondrules.

The exploding streak was especially visible over the San Francisco Bay Area and other parts of Northern California, with reports of a bright fireball and loud boom from Santa Cruz County to Mendocino County.

Warm temperatures and cloud-free skies made the bright light more visible.

Arlington, Washington - Halloween proved to be an interesting night for law enforcement in at least four Western Washington counties after reports of a meteor falling to Earth.

The Snohomish County Sheriff's Office said deputies investigated a possible meteor falling somewhere near I-5 and Exit 212, between Stanwood and Arlington.

K9 Officers also responded, but nothing was found.

Deputies cleared the scene, but said they "assume it is a meteor, unless we hear otherwise."

An Arlington police officer confirmed seeing something fall from the sky.

The Federal Aviation Administration said they also fielded calls from people who reported they saw a meteor.

So far, nothing has been found.
