Reports Report 1012ca (Event 1012-2017)

Observer
Name Brad K
Experience Level 3/5
Remarks I was watching TV, sitting in my living room, facing out the living room window with my wife when we heard a loud boom and saw a brief dull yellow flash. We both jumped up and tried to figure out what happened. Eventually I assumed it was thunder and lightning because it was a rainy night. But, there was only one instance and the sound was not the typical loud "crack" of close thunder but a loud "boom" with a near simultaneous flash of dull yellow. When I saw the news reports the following day (March 17, 2017) of a fireball seen over southern British Columbia and western Washington state I realized that what we heard and saw was likely the same event--probably a meteorite entering the atmosphere.
