Woodn't It be Luvverly?

Interesting news that the use of annual tree rings (dendrochronology) to determine dates of archeological events can be made more precise (https://www.theguardian.com/science/2016/aug/17/traces-of-sun-storms-locked-in-tree-rings-could-confirm-ancient-historical-dates-astrochronology). A Japanese worker has found that solar storms (often reasonably well-documented) can lead to a 20-fold increase in Carbon14 in the associated ring (the age of rings-only living in their year- is generally estimated by looking at the ratio of Carbon12 to Carbon14). These 'outliers' would facilitate a more accurate recalibration of the age of rings in ancient wood sections.
