Intermittent clouds at the time of observation, however the seeing was average. Solar Activity is Low with 6 C-class flares in the previous two days.  AR2665 is barely visible at S7W87 degrees and still covers an area of 450 millionths with three spots just before it disappears.  However, the close up in Ha still shows the “walls” and plasma stream above it very nicely. It is great that we could observe some nice Solar features in Ha, especially some nice filaments and prominences.  A very nice sun today!!
