This mid western fireball event was followed by three more fireballs in different parts of the country a few hours later in the night. The three followup fireballs all occurred within 15 minutes of each other near 5:00 UTC time. AMS Event #313, over Missouri happened just a few 100 miles away from the earlier event in Ohio. AMS Event #314 was reported in California and a forth confirmed fireball, AMS Event #316 was reported in Florida.

These fireballs and meteor events are coming in waves.
Are these waves of events growing in number and extent?
On the surface of things, it certainly looks like a curve steepening upwards.
