In point of fact, the meteor was something like 30 km when it exploded. It was over north Waterloo and I was north of St Agatha. Two spherical clouds, and two explosions. Unfortunately, I was dealing with a goat that was trying to eat an oil truck's fuel line, goats having this optimistic 'Well, maybe it has become edible since they last time I tried this' worldview, and I missed seeing the explosions.
