So big that the heat of atmosphere entrance failed to dissipate it. /s
overcast night in late June of 1967 while driving eastbound late at night near Detroit the sky suddenly became greenish, peaked in its greenish brightness, then diminished to what it had been.....all of this took less than ten seconds. It was so astonishing to me that I stopped the car. The next morning the news was that it was a huge meteor arriving through the atmosphere on a south to north trajectory and it had actually landed waaaay north in a sparsely populated area of northernmost Canada.
