Distribution of the latitude of coronal off-limb structures per month in 2021. Row 1 corresponds to January and row 12 to December. Notably, the two expected peaks in latitude (corresponding to the active latitude belts) are not consistent across the hemispheres throughout the months, revealing a strong N-S asymmetry. There is a predominance of coronal activity in the southern hemisphere at the beginning and end of the year, while the northern hemisphere exhibits either equal or greater coronal activity during the middle of the year.
