Gentle giant sunspot region 2192

Sunspot region 2192 has grown today to a size of 2700 millionths of a solar hemisphere making it the largest sunspot region in almost 24 years. Sunspot region 2192 is now even larger than sunspot region 486, which was the source of several strong solar flares almost exactly 11 years ago. Sunspot region 2192 has however been relatively quiet since the X1.6 solar flare (no associated coronal mass ejection) that occurred yesterday.
