What happened
The Anglo-Saxon Chronicle's entry for 793 begins with dread. That year terrifying omens came over the land of the Northumbrians: great sheets of light rushing through the air, whirlwinds, and fiery dragons flying across the sky. A great famine followed, and soon afterwards 'heathen men' fell on the church of God at Lindisfarne, looting and killing. It was the raid usually taken as the start of the Viking Age in England. The Chronicle dates the raid to the sixth day before the ides of January, but historians follow the Annals of Lindisfarne and read it as 8 June, which suits a summer sea raid. The fiery dragons have become one of the best-known medieval sky reports, and appear in collections of historical aerial phenomena alongside the Clonmacnoise ships and the Sigiburg shields.
The original account
A.D. 793. This year came dreadful fore-warnings over the land of the Northumbrians, terrifying the people most woefully: these were immense sheets of light rushing through the air, and whirlwinds, and fiery, dragons flying across the firmament. These tremendous tokens were soon followed by a great famine: and not long after ... the harrowing inroads of heathen men made lamentable havoc in the church of God in Holy-island, by rapine and slaughter.

The official explanation
Astronomers and historians usually read the 'immense sheets of light' as an aurora borealis, which at Northumbria's latitude can appear as moving curtains and rays, and the 'fiery dragons' as bright fireballs or meteors. 'Dragon' was a common medieval word for a fiery meteor. Others treat the omens as literary framing: chroniclers writing after the Lindisfarne disaster looked back for signs that had foretold it, and grouped them with the famine.
The anomalous case
Even on the conventional reading, the entry records more than one kind of phenomenon at once: broad moving lights, whirlwinds, and distinct fiery flying forms that the writer separates from the general glow. The word 'dragon' suggests elongated, apparently self-propelled bodies crossing the sky, which modern witnesses might call cigar- or serpent-shaped luminous objects. The Chronicle says the people were terrified, which points to something beyond familiar northern lights. The same mid-8th-century decades produced the Irish annals' ships in the air (c. 749) and the Frankish flaming shields at Sigiburg (776). Researchers such as Jacques Vallee have pointed to clusters like this as evidence of waves of aerial reports in the early medieval period.
The strongest argument that this was something genuinely unknown or classified, with each claim attributed to the person who made it.
