Apr, 4 BCE (or BC) Chinese astronomers observe and record for about a month a `po star' towards the direction of the modern constellation of Aquila. Wang et al. (ApJ, 569, L43, 2002) argue that this `po star', unlike most others which are now believed to be comets, was actually a hypernova (a supernova like SN 1998bw which had much more kinetic energy release than the typical value), and that the soft gamma repeater SGR 1900+14 is the neutron star created in this event.
1054 AD SUPERNOVAE DISCOVERED, ASTRONOMERS IN CHINA & JAPAN
Reported New Star In Constellation Taurus. This was later established to be a supernova which was the birth of the crab nebulae.
I'm uncertain about whether this refers to supernovae or meteorites. The 'lightning' would suggest the latter; supernovae become bright instantaneously, all right, but they take a while to fade.
