Low solar activity, 2197 returns, coronal hole effects
Solar activity is at low levels (C-class solar flares only) despite the presence of sunspot region 2209 which still has a Beta-Gamma-Delta magnetic layout. Why is it so quiet and can we still expect strong solar flares from this sunspot region? We are also seeing the appearance of a new sunspot region near the east limb which is likely the return of sunspot region 2197. Back here on Earth we see continuing but waning coronal hole high speed stream effects. High latitude locations have been experiencing fantastic auroral displays for several days now. Our header image was taken just a few days ago by Durwood Mark Collier from Vermont, USA. Stunning!
