Top panel: variations of the CH areas during CR 2119–2130 (January–November 2012) in arbitrary units. Solid line – the total CH area; dashed-dotted line – the maximum value of the CH area in the current rotation obtained from the SDO/AIA images at 193 Å. Dotted line – the daily sunspots numbers averaged over each rotation (in arbitrary units). Bottom panel: variation of the SW density flux during CR 2119–2130. Solid line with crosses – the total SW density flux; dashed line with triangles – the slow SW density flux (V < 450 km s−1); dashed-dotted line with squares – the fast SW density flux (V > 450 km s−1).
