A fireball streaked across the skies of Western Minnesota and Northern Wisconsin at about 1:15 AM in the morning on Friday December 11th.
Night sky observers reported seeing a bright green flash that turned night time darkness into near daylight to the local National Weather Service Office in Grand Forks, ND. Other reports were made to the Duluth, MN office as well.
Interestingly, the Beckers County Sheriffs Department reported a similar occurrence about a month ago. Conditions were foggy, so it was difficult for them to tell where the object was headed.
The Geminid Meteor shower is just about to reach its peak over the next couple of days. The fireball over North Dakota and Minnesota may be related to the Geminid meteor shower, or it could be a sporadic hunk of rock that just happened to enter the Earth's atmosphere.
