This report has been linked to the following event: Event 2823-2022
NameChris C
Experience Level3/5
RemarksI may have slightly misunderstood the first orientation/direction question where you can angle the trajectory. I marked it as having travelled parallel to the horizon, which seemed like the best way to convey that it passed over my head, or at least over a point slightly to the east of me. If it didn't pass right through the zenith then it must have been 75° or more elevation midway through its trajectory.The fireball was bright and sudden enough that I flinched instinctively as if expecting an explosion. The first couple of seconds I didn't see the fireball directly as I was not looking up. I noticed a light come on as if clouds had cleared to reveal something at least as bright as the full moon, but more suddenly than that could happen, more like an artificial light switching on. After a second or two of confusion at where the light could be coming from, and realising the shadows were moving, I looked up and saw the fireball pass overhead and then fragment and fade to my north. I have once or twice seen meteors that I would describe as fireballs, but this was by far the brightest.

Concurrent Sound
Delayed Sound
RemarksA single distant low pitch boom 3.5 to 4 minutes after the fireball. I don't know if this is too long a delay to be connected. I couldn't determine the direction of the sound. It was short duration but muffled, not a very sharp bang as if a heavy object had been dropped nearby. This was in a fairly quiet nighttime environment and although there is some potential for traffic noise and railway operations nearby it sounded more distant than any of that.
Persistent train
Terminal flash
RemarksThere was a single large light, and towards the end of the fireball at least one smaller light in parallel very close by, as if having broken off. It all faded about the same time. I didn't detect a colour difference between the fragments. All seemed green-ish white.
