- •
Height new high-quality archeointensities were obtained for Spain.
- •
Several short-lived regional intensity maxima are confirmed for the last 2000 yrs.
- •
Intensity rates larger than 10 μT/century are observed.
- •
Available data and models suggest that the 800 AD event may have a predominantly non-dipolar character.
