The interpretation of the strong 14-C variation around AD 775 as one (orseveral) solar super-flare(s) by, e.g., Usoskin et al. (2013) is based onalleged aurora sightings in the mid AD 770s in Europe: A "red cross/crucifix"in AD 773/4/6 from the Anglo-Saxon Chronicle, "inflamed shields" in AD 776(both listed in the aurora catalogue of Link 1962), and "riders on whitehorses" in AD 773 (newly proposed as aurora in Usoskin et al. 2013), the twolatter from the Royal Frankish Annals. We discuss the reports about these threesightings in detail here. We can show that all three were halo displays: The"red cross" or "crucifix" is formed by the horizontal arc and a vertical pillarof light (either with the Sun during sunset or with the moon after sunset); the"inflamed shields" and the "riders on white horses" were both two mock suns,especially the latter narrated in form of a Christian adaptation of the antiquedioscuri motive. While the latter event took place early in AD 774 (dated AD773 in Usoskin et al. 2013), the two other sightings have to be dated AD 776,i.e. anyway too late for being in connection with a 14-C rise that startedbefore AD 775. We also sketch the ideological background of those sightings andthere were many similar reports throughout that time. In addition, we present asmall drawing of a lunar halo display with horizontal arc and vertical pillarforming a cross for shortly later, namely AD 806 June 4, the night of fullmoon, also from the Anglo-Saxon Chronicle; we also show historic drawings ofsolar and lunar halo crosses from G. Kirch and Helevius and a modernphotograph.

Presumable European aurorae in the mid AD 770s were halo displays
