Few clouds with average seeing.  Solar Activity remains Very Low with one active region.  The only active region, AR2659, has more than doubled its active region area to 170 millionths and has evolved from a Dsi to an Dai on the McIntosh scale, while its spot count increased to 12.  An interesting filament can be observed at the Eastern limb.
