AR12109: Gentle giant!

Four logs of a 'giant' spot group - with, at times, mixed polarities in a Delta configuration. And yet, no flares greater than GOES type C? Note the strong umbral fields in the big preceding spot: 2600G on the tenth. The C4 on the fifth was very 'pretty' - but nothing stronger? Its area reached 800 units - Earth is shown for scale. Watch for this site at the east limb around August first for a possible return performance.
