Abstract
Evidence of a rapid increase in atmospheric radiocarbon (C-14) content in AD 774-775 was presented by Miyake et al. (2012), who observed an increase of about 12 parts per thousand in the C-14 content in annual tree rings from Japanese cedar. Usoskin et al. (2013) report a similar C-14 spike in German oak, and attribute it to exceptional solar activity. If this phenomenon is global in character, such rapid changes in C-14 concentration may affect the accuracy of calibrated dates, as the existing calibration curve is composed mainly of decadal samples. Single-year samples of dendro-chronologically dated tree rings of deciduous oak (Quercus robur) from Kujawy, a village near Krakow (SE Poland), spanning the years AD 765-796, were collected and their C-14 content was measured using the AMS system in the Leibniz Laboratory. The results clearly show a rapid increase of 9.2 +/- 2.1 parts per thousand in the C-14 concentration in tree rings between AD 774 and AD 775, with maximum Delta C-14 = 4.1 +/- 2.3 parts per thousand noted in AD 776.
