2018 January 14 - 17 Sun - development of AR12696
On January 13, the whole set of prominences on the SEE limb "landed" on the disc, producing a huge filament.
On Jan. 14, a strong flare-filament showed up on the eastern end of this filament, indicating the formation of an Active Region. However, no sunspot was seen.
On Jan. 15, this flare-filament has developed into a complex and very active structure, yet no sunspot is seen.
On Jan.16, more flares and filaments show up in this region, and 2 tiny sunspots also show up. This is now numbered as AR12696.
Today, the sunspots have grown larger with multiple umbrae.
