That wasn't the comet, you likely saw a bolide, a super bright meteor. The comet is barely visible and doesn't change noticeably in brightness over the span of seconds. (More like days and weeks) Still, bolides are incredible in their own way.

That's a meteor. I saw one exactly like that in Reunion (what a coincidence) a few years ago.

Comets don't disappear.

I’m confused. I don’t understand this post.

ZTF isn’t a flash in the pan. It’s just slow and steadily moving by.

That's not the way comets work. That's not the way they work at all.

That's not a comet. But it is something very special to see. I've seen one once that was very similar to what you are describing. Once in a lifetime almost.

What’s with the language? There are children on this sub.
