Finding that the sky is blue is not unusual, unless it's 1:15 in the morning.
That's what happened early Friday when observers from western Minnesota to northern Wisconsin reported seeing a bright blue or green flash in the sky.
The National Weather Service in Grand Forks, North Dakota, logged a call at 1:25 a.m. from someone 15 miles west of Bemidji, Minnesota, who reported the sky looked green.
The weather station then heard from a sister station in Duluth, Minn., which passed along observations from law enforcement agencies in Wisconsin, where a huge fireball was seen near the town of Fifield that created temporary mid-day brightness, said Bill Barrett, a Weather Service official in Grand Forks.
Officials suspect the phenomena was a meteor, as this week marks the peak of the Geminid meteor shower, Barrett said.
A Becker County Sheriff's Department deputy was dispatched to investigate two reports of lights in the sky about 1:36 a.m., Sheriff Tim Gordon said.
The reports came from Highway 10 near Frazee, Minn., and Highway 34 east of Detroit Lakes.
Nothing was found, but the area was checked to make sure it wasn't a downed plane, Gordon said.
Gordon said there was ice fog in the sky and it's likely that whatever the object was, it appeared to be closer to the earth than it actually was.
He said the sheriff's department received similar reports of lights in the sky about a month ago, when weather conditions were similar and another meteor shower was occurring.
There have been other strange lights in the sky in recent days and weeks.
Earlier in the week, a bright ball of blue light spotted over Norway, which was also caught on video, is now believed to have been a Russian missile test that went bad.
In early December, a bright ball of fire was seen over one of the Hawaiian islands. A meteor is suspected in that sighting.
