quivering

AR4431, close to 8 o'clock limb, has grown fast since yesterday and shows a big Earth-sized dark core. The other sunspots stay stable in size as well as in magnetic configuration, solar activity is in low C-class level for the last two days. Poor seeing after clouds finally receded in the afternoon.
