This flowchart is missing “Swamp gas from a weather balloon was trapped in a thermal pocket, and refracted light from Venus”
They forgot “is it followed by a bright flash and mushroom clouds?” → nuke, so grab some whiskey and make your peace because you’re probably too close.
Is “fireball” a technical term here? Because I only know the wizard kind and they do end in a dramatic explosion.
“Fireballs and bolides are astronomical terms for exceptionally bright meteors that are spectacular enough to to be seen over a very wide area. … A fireball is an unusually bright meteor that reaches a visual magnitude of -3 or brighter when seen at the observer’s zenith. … Fireballs that explode in the atmosphere are technically referred to as bolides although the terms fireballs and bolides are often used interchangeably.”
Thanks!

What if it’s big and moving? And burning my retina too ?
