Sketch based on the HMI magnetogram observed at 09:00 UT on 2016 September 24. Black and white areas mark the negative and positive polarities, respectively. Arrows indicate the direction in which different features moved over the course of the day. The black semi-circle denotes the region around P₁ with moat flow and MMFs. The black lines with vertical arrows mark the extent and features belonging to DAR and EAR, also labeled with upper- and lowercase letters.
