What a difference a day makes.....
AR 720 just burst on the scene, apparently from nowhere, now it's bigger and more active than AR 719 which we've been following for the past couple of weeks.
Interestingly, if you look at my image of the 23rd, just above the active AR 719 you can just make out an "anomaly" - a small dark patch - this quickly developed into AR 920!
Who said the sun was quiet??????!!!!!
