Explanation: What makes a meteor a fireball? First of all, everyone agrees that a fireball is an exceptionally bright meteor. Past that, the International Astronomical Union defines a fireball as a meteor brighter than apparent magnitude -4, which corresponds (roughly) to being brighter than any planet -- as well as bright enough to cast a human-noticeable shadow. Pictured, an astrophotographer taking a long-duration sky image captured by accident the brightest meteor he had ever seen. Clearly a fireball, the disintegrating space-rock created a trail so bright it turned night into day for about two seconds earlier this month. The fireball has been artificially dimmed in the featured image to bring up foreground Lake Louise in Alberta, Canada. Although fireballs are rare, many people have been lucky enough to see them. If you see a fireball, you can report it. If more than one person recorded an image, the fireball might be traceable back to the Solar System body from which it was ejected.

Thank you for your posts. This one, the Fireball over Lake Louise was spectacular!
If “you see” a kitty cat...
Question: Do we need NASA?
THIS one is among the best pics in the serious.
Asteroid smacking of da Erf is WAY more of a risk to Western Civ than Gorebal Warning.
“...Do we need NASA?...”

To do what?
I guess it depends on what you mean by “need”.
Looks like when I put those JATOs on my wagon.
I think I did come down in Canada.
bttt
I saw one with two astronomy buddies around 1989 at our dark sky site. It lit everything up like daytime, and we could see the flames rolling off of it. There was quite a bit of green color in it. It went almost straight East to West and broke apart, leaving a smoke trail for about 20-25 minutes afterwards.
Haven’t seen anything like it since……😮
I saw another just a few months ago moving east to west near the Superstition Mountains near Mesa, AZ. Really bright, but briefer than the Vegas one. Both were mostly green in color with a little red mixed in.
😮 stunning
Spectacular! Thanks!
I have been to Lake Louise a couple of times, both in May. Spectacularly beautiful place but I have never seen the lake when it wasn’t partly covered in ice.
Nice, thanks for sharing!
Definitely pucker time if you have seen a handful of sci-fi and other scary movies.
That is Ferengi vessel firing.
