AR11808 only joined us a few days ago and is already showing itself having some interesting activity. However on the limb another spot has just rounded onto the disk announcing itself arrival with a crown prominence as it spits small jets of plasma outwards from the sun. All todays shots are rather soft as I was being greedy with the focal length - i was shooting at 3200mm with the 100mm PST mod, with the heat of the late afternoon I should have really backed off to 2000mm or 1600mm fl really. Oh well! These have come out!
