Just after the peak of the 2009 Leonid Meteor Shower, an explosion that turned night to day occurred on 18 November 2009. An asteroid that was not associated with the Leonids was seen and felt just after midnight MST. Witnesses in four states saw the incoming object and felt the ground shake from a 0.5 to 1.0 megaton explosion just above the ground surface.
Six hours after the explosion, an electric blue colored cloud was seen over two states. The strange clouds could have been residual material from the asteroid’s entry and demise.
