Meteor hunters are swarming the Flagstaff and Sedona areas in hopes of finding remnants of a fireball seen in the area Saturday night, accroding to the Daily Sun. The Coconino County sheriffs office and the Coconino National Forest were bombarded with people hoping that some part of the meteorite made it to the ground, although there is no evidence that occurred.
Jeff, who blogs at the Sun Blog, describes at least two separate fireballs and speculates on their origin.
