Events

Summer – An Arab Saracen fleet appears before Pisa, but departs again. The Pisans take their fleet to sea and chase the Arabs down to Southern Italy where, in the Battle of Reggio Calabria, the Pisan fleet defeats the Arabs.
Summer–Autumn – Danish Viking raiders led by Sweyn Forkbeard raid south-eastern England from the Isle of Wight to Reading in the Thames Valley where they overwinter at the Wallingford river crossing.¹
Brian Boru visits Ulster, and remains unchallenged.

A major eruption of the Mount Merapi volcano on Java causes devastation throughout the centre of the island (which it covers with volcanic ash) and to the Javanese Hindu Mataram Kingdom.²

April 30 – The brightest supernova ever recorded, SN 1006, occurs in the constellation of Lupus. It is observed and described in China, Japan, Iraq, Egypt, and Europe and possibly depicted in North American rock art. Modern astronomers now consider its distance at about 7,200 light-years. The supernova provides enough light to read by on a night with a dark moon.³
