1609 in Gangwon Province
There are other more fanciful descriptions, but it's hard to deny that what they're basically talking about is a meteor shower.
There is one other account from Gangwon that is often used to claim UFOs, coincidentally from the exact same year as the obvious meteors, but it goes beyond ridiculous:
So he saw a red white and blue flag about 3 feet long in the middle of his garden, that could fold like a rainbow, that then rose and turned red all over, then turned into beautiful white clouds, then flew into the sky and split into two pieces with one piece flying away, then made a bunch of crazy noises.
That sounds NOTHING like a modern UFO sighting. It sounds like a bunch of random shyt thrown together that someone made up.
Here is the actual text of the Nuremburg event:
Here is the actual text of the Basil event:
Notice, once again, that those accounts sound nothing like modern UFO events. Both of them are completely focused on the sun, involve the sun changing shape, and then start talking about hundreds of objects of all sorts of shapes coming out of the sun. Because of the mention of arcs and crosses, many people think it could be a very fanciful, exaggerated description of a sundog event
Notice the dimming of the sun, exactly like the account, the two red arcs coming out, exactly like the account, and the cross shapes. It's not an exact match, but it's a much closer match than the modern UFOs.
That's the entire list from your link for the 1500s-1600s, and this isn't even ONE account that sounds anything like a modern UFO sighting.
