据报道，4月17日晚上约11时半，万锦一名市民驾车时看见一个明亮的火球从天而降照亮了Lake Simcoe附近的天空。他说火球就在你眼前坠落，看起来像烟花。一瞬间绿色、蓝色的光照亮了夜空。当它飞过头顶时，它变成了明亮的橙色、黄色，然后爆炸成三块。如果它真的是一个火球的话，那就太神奇了。

天文学家认为，这是颗陨石，可能落在了Lake Simcoe东岸附近，就在Argyle的北部。火球是流星体发出的光芒，比金星还亮，而陨石是流星体经过大气层后幸存下来的碎片，降落在地面上。

Western University物理和天文学系的科学家Denis Vida证实，这次火球事件被十几台全天空照相机捕捉到，也被全球流星网络(Global Meteor Network)的几个由公民科学家操作的照相机拍到。有许多小的陨石降落在地面，最初的流星体质量被认为约为10公斤，这意味地面上可能有几十上百克的物质。

到4月19日，美国流星协会( American Meteor Society)收到了30多份关于火球在天空中飞驰的目击报告，范围从最东边的密歇根州的Ann Arbor到纽约州的Albany。
