> I'm not aware of any stars "disappearing" around then.  Tycho brahe is
credited with observing the first supernova in 1572.   A supernova is about
the only reason a star would disappear.  
> I do find it interesting about brahe's "credit" when supernovas have bee
observed in earlier times.  I believe Chinese astronomers observed the nova
that created the crab nebula, but I'm not 100% sure on that. 

Also, Chinese and Korean astronomers were keeping records of sunspots since
about 50 BC, as well as records of nova. I believe their records of comets and
nova are considered complete. Their records of sunspots are less complete
because sunspots are hard to observe with the naked eye.
