On 22 June 2019, around 21:26 UT (17:26 local time), a roughly 5-metre object entered the atmosphere over the Caribbean Sea, and exploded at an altitude of about 25 km over the sea surface, releasing an energy roughly equivalent to 3 kt of TNT. The explosion was first detected by the Geostationary Lightning Mapper (GLM) instrument on board the GOES-16 geostationary satellite.

Close approach fact sheet for asteroid (3122) Florence. The fly-by is not very close to the Earth, but the object is large in size.

A small size asteroid will approach the Earth on 12 October 2017. The expected minimum distance is just above the geostationary ring, thus being a good target for radar observations.

The asteroid ground track is provided below starting one day before the closest approach and extending for 1.5 days. The curve represents the movement of the sub-asteroid point over the Earth along the mentioned time interval. The track starts in the Pacific ocean at magnitude 16 and progresses westwards.
