There is no smoke without fire. Looking a little:
Yields a few gems:
535-536 Java Volcano explosion
536 "the darkest year. no stars for three months"
535-546 nuclear winter without nuke (with volcano explosion)
540 suspected meteor with weather effects felt around the globe
Note that there are very few asteroid impact events noted. (See 1490, 1492!!).
So it is possible that there were several in that period and only a few got
noticed and recorded.
That timeline is amazing. It is a major effort and I think that it deserves some
praise. It's a great website.
