Clear and good seeing before the clouds started to come in.  Solar Activity remains Low with one C-class flare in the last two days.  AR2665 is the only Active Region covering 310 millionths and 15 Sunspots.  The nice filaments of the last few days have badly decayed.  A very large prominence is visible on the Easter limb at approx. the same latitude as AR2664.  It measures 65,000 miles wide and reaches 22,000 miles above the solar surface.  I did capture 50 frames over a period of 50 minutes and spend quite some time processing this and created an animation.  One can see very nicely the intertwined streams of plasma moving around.
