Heat map and computed trajectory of the July 22nd fireball event over Indiana, USA on Friday July 22, 2022, at 01:52 EDT (05:52 Universal Time)

Nearly 150 reports from 8 States

The AMS received nearly 150 reports and many spectacular videos displaying a fireball event that occurred over Indiana and surrounding states on Friday July 22, 2022, at 01:52 AM EDT. The AMS #2022-4188 event was mainly seen from Indiana, but we also received reports from Ohio, Illinois, Wisconsin, Iowa, Missouri, Kentucky, and northern Alabama. The initial computer generated trajectory shows that this fireball entered the atmosphere over Advance, Indiana and  its flight ended near Burlington, Indiana. Both of these towns lie just northwest of Indianapolis. There are no reports of loud booms with this event, which indicate that the fireball completely disintegrated while still high in the atmosphere.

A fireball is a meteor that is larger and brighter than normal. Most meteors are only the size of tiny pebbles. A meteor the size of a softball can produce light equivalent to the full moon for a short instant. The reason for this is the extreme velocity at which these objects strike the atmosphere. Even the slowest meteors are still traveling at 10 miles per SECOND, which is much faster than any round fired from a firearm. Fireballs occur every day over all parts of the Earth. We normally receive about 100 reports each day. It is rare though for an individual to see more than one or two per lifetime as these short-lived events also occur during the day, on a cloudy night, or over a remote area where no one sees it. Observing during one of the major annual meteor showers can increase your chance of seeing another one of these bright meteors. The next major annual meteor shower will occur on the night of 12/13 August 2022, when the Perseid meteor shower reaches maximum activity.

The map below displays just how widely this object was visible over Midwestern USA. Fireballs can become visible at altitudes near 100 miles, allowing them to be visible over a large area. Visit the event page for this fireball to view the videos and read comments from the witnesses.

Fireball, Bolide?

Several thousand meteors of fireball magnitude occur in the Earth’s atmosphere each day. The vast majority of these, however, occur over the oceans and uninhabited regions, and a good many are masked by daylight. Those that occur at night also stand little chance of being detected due to the relatively low numbers of persons out to notice them.

Additionally, the brighter the fireball, the more rare is the event. As a general thumb rule, there are only about 1/3 as many fireballs present for each successively brighter magnitude class, following an exponential decrease. Experienced observers can expect to see only about one fireball of magnitude -6 (crescent moon) or better for every 200 hours of meteor observing, while a fireball of magnitude -4 (Venus) can be expected about once every 20 hours or so.
