Alaska Highway Troopers and others in the state’s Bureau of Land Management are investigating an alleged sighting of an extraterrestrial object in the Arctic.

An online sighting report by a member of the public was sent to the Anchorage office of Alaska Highway patrol late Thursday.

A spokeswoman said investigators have not determined if the sighting is related to the disappearance of four men on a cruise ship in June, but are looking into the possibility.

Alaska Highway Patrol spokesman Matt McFarland said investigators are also checking on a report that a woman saw an object on the road.

The trooper said the trooper was not aware of any further sightings.

The report was sent by a resident who was traveling along Highway 49 near the town of Fairbanks on June 2, according to the report.

The woman said she saw an alien object in her rearview mirror and that it appeared to be about 20 feet long and about two feet wide, according the report, which was obtained by the Anchorage Daily News.

The report did not say how the object was spotted or what the object looked like.
