AR12671 in Ha - 15th August

A new active region coming around the limb with plenty of small flaring activity.  The 203mm Airylab HaT was used but a mobile westerly air stream meant the seeing was never going to be the best.  I took a number of images and this one was the best of the bunch.  I was out early to observe and was surprised how much later the sun was now starting to rise as I realised we are closer to the autumn equinox than the summer solstice - seasons a changing!
