*[1] A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET). At 95 minutes before it impacted Earth’s atmosphere, NASA’s Scout impact hazard assessment system, which monitors data on potential asteroid discoveries, gave advance warning as to where and when the asteroid would impact.
*[2] This is the eighth time in history that a small Earth-bound asteroid has been detected while still in space, before entering and disintegrating in our atmosphere.
*[3] The asteroid’s impact produced a bright fireball, or bolide, which was seen from as far away as the Czech Republic and may have scattered small meteorites on the ground at the impact site about 37 miles (60 kilometers) west of Berlin.
I'm not sure how I feel about 95 minutes warning [1], had it been larger would there be more warning or would that be the alert time had it been heading for (say) Berlin.
I'd be interested in knowing how many were missed during the time they had advance warning for the eight seen [2].
[3] Damascus Sky Iron!!
very probably small pebble sized and smaller pieces that mostly would be hard to find
