Magnetic activity at Mars - Mars Surface Magnetic Observatory

► Significant magnetic disturbances are observed close to crustal magnetic anomalies at the day-side. ► The disturbances are not confined to the south but occur also in large parts of the equatorial region. ► Close to the medium sized anomalies the data pattern indicates the presence of current loops. ► Far from crustal anomalies ground signals are expected at the night-side and during storm events. ► The Mars Surface Magnetic Observatory, i.e. the MSMO experiment is presented.
