Clear Skies on the 9th, with reasonable seeing conditions (3/6) sufficient to also bring out the SV80 for as close-up in white light/continuum.  The dominant active region today is AR2257 although its size is a modest 170 millionth.  Both close-ups made with the SM40, and the SV80, used a 3x barlow.   The white light image is a stack of 5 hand selected images out of 1200, stacked and sharpened in Registax6 and processed in Photoshop.
