Below is an interesting paper about the A.D. 774–775 Carbon-14 Spike. Timothy Jull, A. J., I. P. Panyushkina, T. E. Lange, V. V. Kukarskih, V. S. Myglan, K. J. Clark, M. W. Salzer, G. S. Burr, and S. W. Leavitt, 2014, Excursions in the 14C record at A.D. 774–775 in tree rings from Russia and America. Geophysical Research Letters. 10.1002/2014GL059874, 7 pp.
“Our results confirm an abrupt ~ 15‰ 14C activity increase from A.D. 774 to 776, the size and now the hemispheric extent of which suggest that an extraterrestrial influence on radiocarbon production is mostlikely responsible.
