Fireball Wednesday Night 4/14
Just after 10 pm CDT Wednesday evening April 14th, a fireball or very bright meteor was observed streaking across the sky. The fireball was seen over the northern sky, moving from west to east. Well before it reached the horizon, it broke up into smaller pieces and was lost from sight. The fireball was seen across Northern Missouri, Illinois, Indiana, and Southern Wisconsin. Several reports of a prolonged sonic boom were received from areas north of Highway 20, along with shaking of homes, trees and various other objects including wind chimes. As of late Wednesday evening, it is unknown whether any portion of this meteorite hit the ground.
The fireball was caught on a webcam from UW-Madison AOS/SSEC.
The fireball was also caught by a Howard County Iowa Sheriff’s Deputy.
This video was provided by KWWL TV.
Also, the Doppler Radar from the National Weather Service in the Quad Cities appeared to capture a portion of the smoke trail from the fireball at 0302z (1002 PM CDT), as seen in the image below. It appears as a thin line extending across portions of Grant and Iowa Counties in Wisconsin. This trail is positioned nearly 88 miles north-northeast of Davenport, Iowa at an elevation of just over 24,000 ft AGL.
