About this image

This came out better than I expected, the seeing was dreadful and clouds came over preventing me from imaging the rest of the active region AR4114, inset showing extent of the Active Region is from a whole disk image. I always prioritise whole disk images as they enable me to calculate the Relative sunspot number and Quality Number, both measures of overall solar activity.
