Observations of December 2006 events

This article presents observations of various solar events and the magnetic field distribution on the Sun's surface in December 2006. It includes data from GOES, ACE LASCO, Hinode, MDI, SOLIS, and McTiernan's code. The observations cover flare activity, the evolution of AR10930, vector field observations, potential field measurements, surface flow maps, and energy analysis.
